Unable to compile TypeScript with "moduleResolution": "bundler" option in v5 #27731
Description
Current behavior
Originally reported by @MasonM in #26308 and closed because of Cypress v13.0.0 - but this release does not fix this
cc @jennifer-shehane @lmiller1990 - ideally #26308 would be unlocked and reopened, if you can do that
Copied issue below:
If you have a TypeScript project using the new "moduleResolution": "bundler" setting introduced in TypeScript 5, any attempts to run tests will cause the following error:
TSError: ⨯ Unable to compile TypeScript:
error TS5095: Option 'bundler' can only be used when 'module' is set to 'es2015' or later.
Desired behavior
Tests run successfully
