Resolve all glob patterns for `files.associations` relative to workspace root

[gremo]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.79.1
• OS Version: Windows 11

Steps to Reproduce:

1. Create the following configuration:

"files.associations": {
    "config/docker/*.cnf": "ini"
}

2. Create a file config/docker/mariadb.cnf
3. Files mariadb.cnf is not recognized as INI file

On the contrary, **/config/docker/*.cnf works as expected, but it would associate also foo/config/docker/test.cnf, which I don't wanto to.

Another use-case of this is that I have the following in my global gitignore:

/.vscode

but obviously some projects use a .vscode directory. Instead of adjusting the project's gitignore file, I instead like to edit .git/info/exclude to the following:

!/.vscode

VSCode doesn't recognize that file as an ignore file, so I would like to add ".git/config/exclude": "ignore" to my files.associations which doesn't work.
