Loading databases in directories named `db-*` fails with error 'does not contain a CodeQL dbscheme'

[smowton]

Describe the bug
Loading databases in directories named db-* fails with error 'does not contain a CodeQL dbscheme'

To Reproduce
Find any old CodeQL database, verify you can load it with the plugin's "Choose database from folder" GUI. Copy it to /tmp/db-test, try to load it from there.

You should get an error Database '/tmp' does not contain a CodeQL dbscheme under '/tmp/db-test'.

Expected behavior
Loading should succeed

Looks like this glob is at fault for misidentifying the database root as a db-$langname dataset stored within it: https://github.com/github/vscode-codeql/blob/main/extensions/ql-vscode/src/databases.ts#L88
