updated playwright.yml - Githubissues

This pull request includes improvements to the GitHub Actions workflow for Playwright tests. The changes primarily focus on adding caching for node modules and Playwright browsers to speed up the test runs.

Here is a summary of the key changes:

.github/workflows/playwright.yml: Added caching for node modules using actions/cache@v2. This caches the node_modules directory based on the hash of the yarn.lock file, which will speed up the installation of dependencies in future runs if the yarn.lock file hasn't changed.
.github/workflows/playwright.yml: Added caching for Playwright browsers. This caches the ~/.cache/ms-playwright directory, which contains the browser binaries used by Playwright. This will speed up the installation of Playwright browsers in future runs.
