glob 7.2.3 is deprecated

Warning from npm install

npm WARN deprecated [email protected]: Glob versions prior to v9 are no longer supported

We didn't allow major updates on glob because it broke the tests. Looks like we can remove this dependency now though

These warnings are not totally under our control since they get reported even when installing dependencies of our dependencies. For instance we depend on @vscode/vsce, which still depends on glob 7.0.6. We get a deprecation warning about that.

Currently we are referencing "glob": "~7.2.3" in the devDependencies, maybe we should remove it if we aren't using it. It looks like the test code reliant on it has been removed

Here are a few issues in dependencies we're using that track glob deprecation:
mochajs/mocha#5148
microsoft/vscode-vsce#1026

vscode-test-cli also uses an outdated c8 that depends on a version of test-exclude that uses a deprecated version of glob: https://github.com/bcoe/c8/blob/main/package.json#L43
