Subject: [PATCH 1/2] playwright-driver: expose selectBrowsers for custom
 browser selection

Expose the underlying browsers function as `selectBrowsers` passthru,
allowing users to create custom browser sets. Note: all browsers are
enabled by default.

Example usage:
  playwright-driver.selectBrowsers {
    withChromiumHeadlessShell = true;
    withChromium = false;
    withFirefox = false;
    withWebkit = false;
    withFfmpeg = false;
  }

Subject: [PATCH 2/2] linkwarden: use chromium-headless-shell instead of full
 chromium

Linkwarden only needs headless browser functionality for archiving web
pages. Switch from the full chromium browser to the lighter
chromium-headless-shell via playwright-driver.selectBrowsers, reducing
the closure size.
