Support phpstan 2.0

[eucyt]

I made adjustments due to breaking changes in PHPStan 2.0.
When the Suppress annotation contains a period, quotes are now required.
phpstan/phpdoc-parser#256

close #622

doc should be updated(probably)

line-bot-sdk-php/.github/workflows/php-checks.yml

Lines 49 to 52 in 5db381c

	- name: Update document
	run: |
	wget https://github.com/phpDocumentor/phpDocumentor/releases/download/v3.3.1/phpDocumentor.phar
	php phpDocumentor.phar run -d src -t docs

how about showing result of git diff in this step?

line-bot-sdk-php/.github/workflows/php-checks.yml

Lines 54 to 60 in 5db381c

	diff=$(git --no-pager diff --name-only HEAD)
	echo "DIFF_IS_EMPTY=$([[ -z "$diff" ]] && echo 'true' || echo 'false')" >> $GITHUB_ENV
	echo "CURRENT_DATETIME=$(date +'%Y%m%d%H%M%S')" >> $GITHUB_ENV
	- if: ${{ env.DIFF_IS_EMPTY != 'true' && github.actor != 'renovate[bot]' }}
	run: |
	echo "There are changes from the auto-generated files by OAS. Please run diff-check.yml and merge the PR generated by it first."
	exit 1
