Support for a regular expression as testMatch config option

[SanjoSolutions]

playwright.config.cjs:

module.exports = {
  testMatch: /.*\.e2e\.(test|spec)\.(js|ts|mjs)/
}

running:

npx playwright-watch test -c playwright.config.cjs

shows the error:

TypeError: Non-string provided as watch path: /.*\.e2e\.(test|spec)\.(js|ts|mjs)/,!node_modules

This works when running Playwright directly with npx playwright test --browser=chromium -c playwright.config.cjs.
