meta(micrometer): Register Sentry Micrometer package

[adinauer]

Register io.sentry:sentry-micrometer version 8.58.0 in the release registry, including major, minor, latest, and SDK aliases.

This makes the new Java integration discoverable through release-registry consumers once its first artifact is published. The change is a standalone PR against master for the sentry-java Micrometer implementation stack.

Related documentation: getsentry/sentry-docs#19463

Keep this PR in draft until io.sentry:sentry-micrometer:8.58.0 is available from Maven Central and the documentation is live. Confirm the recorded release timestamp against the published artifact before merging.

Bug: Alias files were created manually as text pointers instead of being generated as symlinks via the make sync-all-links command, violating documented project standards.
_{Severity: MEDIUM}

Suggested Fix

Remove the manually created alias files (8.58.json, 8.json, latest.json). After creating the full version file (8.58.0.json), run the make sync-all-links command to automatically generate the correct symlinks as required by the project's standards.

Potential issue: The alias files `8.58.json`, `8.json`, and `latest.json` were manually
created with text content pointing to the full version file (`8.58.0.json`) instead of
being generated as symbolic links. The project's contribution guidelines explicitly
state that these files must be created by running the `make sync-all-links` command. If
these files are deployed as plain text pointers instead of symlinks, downstream tooling
expecting to parse JSON from them will fail, breaking release discovery for consumers of
the registry.
