Remove dependency on `path` module for browsers

[pallymore]

Describe the bug

Currently when using the webworker runtime (from @aws/language-server-runtimes/runtimes/webworker) in the browser, consumers are required to provide the path node module, because the initializeUtils file depends on it. path is only available in NodeJS environments, in browsers, there is a polyfill path-browserify but it's been unmaintained for years.

Please remove the dependency on path for webworker runtimes - this was a regression as the same issue happened before but was later fixed.

This appears to be the problematic commit: fa9892e

Please also consider adding integration tests for browser environments to prevent non-browser modules being introduced accidentally.

To reproduce

1. Start a web project
2. Use the webworker runtime
3. bundle the runtime for web (using a tool like webpack 5+)
4. see dependency errors as path does not exist.

Expected behavior

The webworker module should work without using any NodeJS-only dependencies.
