Restore ability to run adhoc maestro cloud release tests for hotfixes

Task/Issue URL: https://app.asana.com/1/137249556945/project/1211760946270935/task/1213422200354215?focus=true

Description

Restores release_tests.yml to allow it to trigger release tests to run on Maestro Cloud from CI from an arbitrary commit hash

Changes:

• Add initial develop checkout so composite actions resolve correctly for hotfix refs
• Remove test-tag input — always run releaseTest
• Rename app-version input to commit-ref (accepts branches, tags, or SHAs)
• Rename workflow to "Ad-hoc Release Tests - Maestro Cloud"
• Remove Asana task creation on failure

Steps to test this PR

• QA optional
• Tested in runs https://github.com/duckduckgo/Android/actions/runs/22862027726 and https://github.com/duckduckgo/Android/actions/runs/22861749518 to run against a tag and a branch

Note

Low Risk
Low risk: changes are limited to a manually-triggered CI workflow, though it affects how release-test runs are checked out and could break ad-hoc testing if refs/actions resolution is wrong.

Overview
Restores/streamlines the ad-hoc Maestro Cloud release testing workflow so it can be run against an arbitrary branch/tag/SHA via a renamed commit-ref input.

The workflow now checks out develop first to ensure local composite actions resolve, always runs the releaseTest Maestro tag (removing the configurable test-tag input), and removes the Asana task creation and related env vars on failure.
