Revert "build(replay): Remove replay version string replacement (#6367)"

[Lms24]

This PR reverts #6367 as the Replay team would like to continue injecting the version separately from the SDK to detect version package version mismatches more easily.

Note: This will not avoid the 7.x bump in the next Replay release, it will just enable a scenario like users use the SDK on e.g. 7.25 and Replay on 7.24 and replay events will have the 7.24 version in their metadata.

Note 2: This makes a very good case for exporting Replay via the SDK to, as it avoids version mismatches all together. Same for Tracing later on...
