This PR fixes
https://github.com/microsoft/playwright/pull/27790#pullrequestreview-1738958803.
Previously this function returns only the first error when some of the
promises fail. But the type annotation suggests that the original
intention was to collect all the errors. This commit fixes the error
values, and unexpected `TypeError: object is not iterable`.
Migrate to version 4 which returns a promise rather than leverages a
callback. -> https://www.npmjs.com/package/rimraf?activeTab=readme
- contains its own types, eliminate "@types/rimraf"
- Parameter `maxBusyTries` changed to `maxRetries`
