Stop installing Playwright browsers in old branches

[desrosj]

In 6.4, the E2E tests switched to using Playwright. Earlier branches continue to utilize Puppeteer (see [56926]).

Recently, the E2E testing workflow in 6.3 and earlier has ​started to ​fail. The failures are caused by the npx install playwright --with-deps command. This step is not necessary for older branches because Playwright is not even used.

This adds an input to the reusable workflow to allow this step to be easily skipped for older branches.

In 60005:

Build/Test Tools: Add input for skipping Playwright steps.

In older branches utilizing Puppeteer instead of Playwright, installing Playwright browsers is unnecessary and resulting in workflow failures.

This introduces a new install-playwright input that allows older branches to indicate that Playwright related steps should be skipped.

See #63117.
