fix(ci): use version regex for SUPPLY_TRACK instead of semver is_stable

[TimeToBuildBob]

Problem

The release-fastlane job uses nowsprinting/check-version-format-action@v4 to determine if a tag is stable, then sets SUPPLY_TRACK accordingly:

if [[ "${{ steps.version.outputs.is_stable }}" == "true" ]]; then
  SUPPLY_TRACK="production"
else
  SUPPLY_TRACK="internal"
fi

The issue: check-version-format-action follows the semver convention where 0.x.x versions are not considered stable (they're "development" versions). Since all aw-android releases are 0.x.x, is_stable is always false, and every release goes to the Play Store internal track instead of production.

This caused the v0.14.0 release run to fail with SUPPLY_TRACK=internal, sending the AAB to the wrong track.

Fix

Replace the is_stable check with a direct regex on the tag version string:

• X.Y.Z (no suffix) → production
• X.Y.ZbN, X.Y.ZrcN, X.Y.ZdevYYYYMMDD, etc. → internal

This matches how the Release workflow documents it:

#   Stable:      0.14.0         → full Play Store production release
#   Beta:        0.14.0b1       → GitHub pre-release, Play Store internal track

Context

Found while investigating the failed v0.14.0 release in issue #176. The other blocker (Target SDK 35 too low) is fixed by PR #179. This PR fixes the track routing so that once #179 merges and the release is re-triggered, the AAB lands in the production track.

Greptile Summary

This PR updates release track selection for Android publishing.

• Uses the tag name instead of the semver stability output.
• Routes bare X.Y.Z tags to the production track.
• Routes suffixed prerelease tags to the internal track.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The release workflow creates lowercase v{version} tags that match the new parsing path.
• The changed job still runs only for tag-based release refs.
