Remove gradle_wrapper_updater feature flag

[kbukum1]

What are you trying to accomplish?

Remove the gradle_wrapper_updater feature flag to enable Gradle wrapper updates for all users by default.

This completes the rollout after successful validation in production with healthy metrics.

Fixes #2223

Anything you want to highlight for special attention from reviewers?

Test stubs were added for wrapper file requests in tests that didn't previously need them, since wrapper files are now always fetched.

How will you know you've accomplished your goal?

• All existing tests pass
• No remaining references to gradle_wrapper_updater in the codebase

@yeikel , the PR is good. I left comment. It will be great to have green pipeline there. Can you do the temporary change?

Reverted temporary check after pipeline succeed. So it is ok to get error from Smoke / smoke (gradle-version-catalog) (pull_request) .
