(FIX) Fix unwanted space when pushing annotations to service

[mlachevre-pass]

Description

Currently if we enable "service: annotations:" annotations are template with wrong indentation and display this error.
Error: YAML parse error on posthog/templates/events-service.yaml: error converting YAML to JSON: yaml: line 8: did not find expected key
After fixing it (a bad space on the range declaration) we observed
Error: YAML parse error on posthog/templates/web-service.yaml: error converting YAML to JSON: yaml: line 14: did not find expected key
And in fact the indentation isn't ok.

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

How has this been tested?

• Download chart locally
• helmfile template without changing the templates folder
• Updating events and web service
• helmfile template doesn't return any yaml error
