[Feature] Allow wildcards for icon filenames

[npearson72]

Is your feature request related to a problem? Please describe.
There are times when I would like to define an icon for a matching wildcard filename. For example, I have different eslint config files, ex:

• eslint-base.conf.mjs
• eslint-react.conf.mjs
• eslint-node.conf.mjs

Today, in order to use an eslint icon for each of these files, I would need to do:

    "filenames": {
      "eslint-base.config.mjs": "eslint",
      "eslint-react.config.mjs": "eslint",
      "eslint-node.config.mjs": "eslint",
   }

What I would like to do is:

    "filenames": {
      "eslint-*.config.mjs": "eslint"
   }
