Fix default loading strategy tests and run Prettier formatting

The default generated_component_packs_loading_strategy was changed to :defer
in commit 4faf810 to avoid race conditions with async loading. This commit
updates the tests to reflect the new default behavior.

Changes:
- Update test for Shakapacker >= 8.2.0 to expect :defer instead of :async
- Update test for Shakapacker < 8.2.0 to expect :defer instead of :sync
- Remove outdated warning expectation since :defer works on all versions
- Suppress ESLint deprecation warning for tsEslint.config
- Auto-format markdown files with Prettier

All 433 gem specs now pass.

 ### For Regular Changelog Updates
 
 1. **ALWAYS fetch latest changes first**:
-
    - **CRITICAL**: Run `git fetch origin master` to ensure you have the latest commits
    - The workspace may be behind origin/master, causing you to miss recently merged PRs
    - After fetching, use `origin/master` for all comparisons, NOT local `master` branch
 
 2. **Determine the correct version tag to compare against**:
-
    - First, check the tag dates: `git log --tags --simplify-by-decoration --pretty="format:%ai %d" | head -10`
    - Find the latest version tag and its date
    - Compare origin/master branch date to the tag date
    - If the tag is NEWER than origin/master, it means the branch needs to be updated to include the tag's commits
    - **CRITICAL**: Always use `git log TAG..BRANCH` to find commits that are in the tag but not in the branch, as the tag may be ahead
 
 3. **Check commits and version boundaries**:
-
    - **IMPORTANT**: Use `origin/master` in all commands below, not local `master`
