Description

Current license-extractor.ts is missing the npm packages license files that needs to be extracted.

const LICENSE_FILES = ['LICENSE', 'LICENSE.txt', 'LICENSE.md'];

....

      // Search for a license file within the root of the package
      for (const potentialLicense of LICENSE_FILES) {
        const packageLicensePath = path.join(packageDirectory, potentialLicense);
        try {
          licenseText = await readFile(packageLicensePath, 'utf-8');
          break;
        } catch {}
      }

This code doesn't match files in different lower/upper case when builds are run on a Linux system where the file system is case sensitive.
Example of packages:
https://www.npmjs.com/package/globals?activeTab=code -> license
https://www.npmjs.com/package/screenfull?activeTab=code -> license

Also there are license files that are not named as expected in the code
Example of packages:
https://www.npmjs.com/package/idb-keyval?activeTab=code -> LICENCE
https://www.npmjs.com/package/estraverse?activeTab=code -> LICENSE.BSD
https://www.npmjs.com/package/stackblur-canvas?activeTab=code -> LICENSE-MIT.txt
https://www.npmjs.com/package/leaflet.markercluster?activeTab=code -> MIT-LICENCE.txt

Fun fact:

British English:
Licence is used as a noun.
License is used a verb.

Previous license-webpack-plugin used was using a regex to find the license file /^licen[cs]e/i.test(path)

I suggest to use a similar principle to loop over files in root project dir and check with a regex like /licen[cs]e/i.test(path)

Minimal Reproduction

1. On a Linux env clone repo https://github.com/tiberiuzuld/repo-app-license.git
2. run npm ci && ng build
3. Observe dist/repro-app/3rdpartylicenses.txt missing license text for the packages mentioned above
