Custom matcher for paths on different OS #744

User story

As a developer I want to have a good signal to noise ration and want to write my tests with as less boilerplate as possible.
Paths are environment specific and cause boilerplate to get properly tested.
Therefor I need a custom matcher for paths.

Existing helper:
os-agnostic-paths

Bad example:

expect(osAgnosticPath(process.cwd())).toEqual(
      expect.stringContaining(
        osAgnosticPath('project-root/other-folder'),
      ),
    );

Suggested matcher:

• expect(myPath).toContainPath('...')
• expect(myPath).toEndWithPath('...')

Good example:

// windows 'C:\Documnets\my-projects\project-root'
// linux '/home/my-projects/project-root'
expect(process.cwd()).toContainPath('project-root/other-folder');
expect(process.cwd()).toEndsWithPath('project-root/other-folder/src');

Acceptance criteria

I want to be able to use the custom matcher in the following libs:

• vitest

Internal logic:

• it handles path differences of all OS
  I want to be able to have different matcher present:
• toContainPath('...')
• toEndWithPath('...')
• the existing code is using the helper, e.g. nx-plugin tests for persist.outputDir
