build(ui-scripts): add prerelease option to the bump script for security releases

[HerrTopi]

Summary

• Adds prerelease as a supported value for ui-scripts bump so security releases can be cut via pnpm run bump --releaseType=prerelease, producing versions tagged x.y.z-SECURITY.N via lerna's --preid=SECURITY.
• Skips writing versioned exports entries to package.json files when the release is a SECURITY prerelease, since those entries are reserved for real minor/major releases.
• also added scripts to package.json to make specific bumps easier

Test plan

• Run pnpm run bump --releaseType=prerelease locally and verify packages bump to x.y.z-SECURITY.0
• Verify no new versioned exports keys are added to package.json files during the prerelease bump
• Run pnpm run bump --releaseType=patch (or minor) and confirm existing behavior is unchanged (normal bump + exports entries added)
