refactor(component-release): remove git-flow and RDKCM_RDKE secret, release directly on feature/component-release

[Copilot]

• Restore git-flow (release start, release publish, release finish) in the workflow
• Configure git-flow to use feature/component-release as both master and develop branch
• Use actions/checkout@v3 with ref: feature/component-release and fetch-depth: 0 (fixes the RDKCM_RDKE auth failure)
• Push only to feature/component-release and tags (no main/develop)
• Keep PR_DESC passed via env block (shell injection fix)
• Keep cleanup step guard for RELEASE_VERSION
• Run validation — passed (CodeQL clean, review comments are intentional design choices)

Original prompt

Problem

The current .github/workflows/component-release.yml workflow uses git-flow which automatically merges release branches into main and develop. This is undesirable because:

1. We don't want releases to merge into main or develop — the release should happen entirely on the feature/component-release branch.
2. The workflow currently fails with an authentication error because it clones the repo using a custom secret (RDKCM_RDKE) that is expired/invalid:

   remote: Invalid username or token. Password authentication is not supported for Git operations.
   fatal: Authentication failed for 'https://github.com/rdkcentral/sysint/'
   

3. The PR description body is interpolated directly in a shell script via ${{ }}, which can break on special characters.

Required Changes

Replace the entire contents of .github/workflows/component-release.yml with the following:

name: Component Release

permissions:
  contents: write

  pull_request:
    types: [opened, edited, ready_for_review, closed]
    branches:
      - feature/component-release

jobs:
  validate-version:
    if: ${{ github.event.action == 'opened' || github.event.action == 'edited' || github.event.action == 'ready_for_review' }}
    runs-on: ubuntu-latest
    steps:
      - name: Validate PR description for version field
        env:
          PR_DESC: ${{ github.event.pull_request.body }}
        run: |
          if ! echo "$PR_DESC" | grep -qiE 'version[[:space:]]*:[[:space:]]*(major|minor|patch)'; then
            echo "ERROR: PR description must include a version field in the format 'version: major|minor|patch' (case-insensitive). Example: version: minor"
            exit 1

Summary of changes:

• Remove all references to main and develop branches — no checkouts, no pushes, no git-flow config for those branches.
• Remove git-flow entirely — no install, no git flow release start/publish/finish. Everything happens on feature/component-release.
• Remove the manual git clone with RDKCM_RDKE secret — use actions/checkout@v3 with ref: feature/component-release and fetch-depth: 0 instead, which uses the built-in GITHUB_TOKEN auto...
