CLI Ingore bugs

[fisker]

Environments:

• Prettier Version: 2.7.1
• Running Prettier via:
• Runtime:
• Operating System:
• Prettier plugins (if any):

Steps to reproduce:

During #12859, I found two possible issues.

Problem 1:

# .prettierignore
/tests/integration/plugins/
!/tests/integration/plugins/extensions/plugin.cjs

$ npx prettier --file-info tests/integration/plugins/extensions/plugin.cjs
{ "ignored": true, "inferredParser": null }

# .prettierignore
/tests/integration/plugins/**/*
!/tests/integration/plugins/extensions/plugin.cjs

$ npx prettier --file-info tests/integration/plugins/extensions/plugin.cjs
{ "ignored": false, "inferredParser": "babel" }

But maybe this is expected, for faster glob?

Problem 2:

I can't find a way to format files inside node_modules

$ npx prettier --file-info tests/integration/plugins/automatic/node_modules/@prettier/plugin-foo/index.js
{ "ignored": true, "inferredParser": null }

$ npx prettier --file-info tests/integration/plugins/automatic/node_modules/@prettier/plugin-foo/index.js --with-node-modules
{ "ignored": true, "inferredParser": null }

Expected behavior:

Maybe "Problem 1" should work the same with or without **/*

Problem 2: when running --with-node-modules should be able to format that file.

# .prettierignore
wp-content/**/*
!wp-content/themes/**/*

I also can't get this to work. I would expect that anything inside the wp-content to be ignored, but make an exception for themes. As is, themes is also ignored. Is this a bug or do I have the wrong syntax?
