Update 3 year old error-stack-parser library with its newer esm version

[matux]

Description of the change

This PR replaces the 3-year old error-stack-parser library to its modern (and maintained) port error-stack-parser-es which provides types as well as being pure esm.

The API and behavior doesn't seem to have changed.

This is needed to make browser tests work under WTR, since browsers don't support cjs thus were complaining about it:

$ npx web-test-runner test/browser.core.test.js --config web-test-runner.config.mjs

test/browser.core.test.js:

 🚧 Browser logs:
      SyntaxError: The requested module './../node_modules/error-stack-parser/error-stack-parser.js' does not provide an export named 'default'

 ❌ Could not import your test module. Check the browser logs or open the browser in debug mode for more information.

Chromium: |██████████████████████████████| 1/1 test files | 0 passed, 0 failed

Error while running tests.

I'm trying my best not to introduce rollup plugins to convert cjs until I absolutely must. I took the plugin road last time and it was very messy (also, because we hadn't migrated to esm, yet), but still.

This is simpler, gives us a maintained lib, improves security, etc.
