fix: use JSON kind for devcontainer updatecli targets (#1846)

* fix: use JSON kind for devcontainer updatecli targets

Switch from file kind with regex patterns to json kind with JSONPath
queries for updating Docker and GitHub CLI versions in devcontainer.json.

The previous file-based approach failed because the search pattern matched
the feature name line, but the version field is on the next line. Using
json kind with JSONPath directly targets the correct fields.

* fix: use bracket notation for JSONPath keys with special characters

* fix: use yaml kind instead of json kind for devcontainer.json

JSON is valid YAML, and updatecli's yaml kind uses yq which handles
bracket notation better than the json kind's JSONPath implementation.

* fix: use file kind with content blocks for devcontainer updates

Use content parameter to identify the specific feature block, then apply
version pattern matching within that block. This avoids JSONPath/yamlpath
syntax issues with keys containing special characters.

* fix: disable devcontainer updatecli manifest temporarily

Disable the devcontainer dependency update pipeline due to updatecli
limitations with JSON keys containing special characters (dots, slashes,
colons). Multiple approaches were attempted (json kind, yaml kind, file
kind with content blocks) but all failed.

Added README explaining the issue and manual update process until a
solution is found.

* fix: move disabled devcontainer manifest outside updatecli.d

Updatecli loads all .yaml files in updatecli.d/ directory, including
.disabled files. Move the disabled devcontainer manifest and its README
to updatecli/disabled/ directory to prevent it from being loaded.

+# Devcontainer Dependency Updates - Currently Disabled
+
+The `devcontainer.yaml` updatecli manifest has been temporarily disabled (renamed to `devcontainer.yaml.disabled`) due to technical limitations with updatecli's handling of JSON keys containing special characters.
+
+## The Problem
+
+The devcontainer.json file uses feature keys with dots, slashes, and colons:
+```json
+{
+  "features": {
+    "ghcr.io/devcontainers/features/docker-in-docker:2": {
+      "version": "v27.0.3"
+    },
+    "ghcr.io/devcontainers/features/github-cli:1": {
+      "version": "v2.83.1"
+    }
+  }
+}
+```
+
+Updatecli cannot reliably target these keys using:
+- **JSON kind**: JSONPath bracket notation fails to find the values
+- **YAML kind**: Yamlpath complains about invalid characters in the path
+- **File kind**: Complex multiline pattern matching is error-prone
+
+## Manual Update Process
+
+Until this is resolved, devcontainer dependency versions should be updated manually:
+
+1. Check latest Docker version: https://github.com/moby/moby/releases
+2. Check latest GitHub CLI version: https://github.com/cli/cli/releases
+3. Update `.devcontainer/devcontainer.json` manually
+4. Test in GitHub Codespaces to verify functionality
+
+## Potential Solutions
+
+- Wait for updatecli to improve JSON/YAML path handling for keys with special characters
+- Consider restructuring devcontainer.json to use simpler feature keys (requires changes to devcontainer spec)
+- Create a custom script to handle these specific updates outside of updatecli
+
+## Re-enabling
+
+To re-enable when a solution is found:
+```bash
+mv updatecli/updatecli.d/devcontainer.yaml.disabled updatecli/updatecli.d/devcontainer.yaml
+```
