[LRNcardozoWDF]

🎟️ Tracking

PM-20288

📔 Objective

Adding a new workflow able to update the sdk to a given version and open a PR. This will be used by the sdk-internal repo when PRs are merged. The ability to test SDK PRs will be introduced in a future PR.

Based on bitwarden/android#5742, with the addition of the downgrade detection.

Test runs:

• Happy path - Update to new version with success https://github.com/bitwarden/ios/actions/runs/17439403637
• Error state - Updating to the same version in main - https://github.com/bitwarden/ios/actions/runs/17435544778
  *. Downgrade detection - Update SDK to e6fa6b6 (1.0.0-unstable-1a2fc24) #1904
