[DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.

This should be able to be fixed by updating the markdown-it module to 14.0.0.

Issue: https://github.com/markdown-it/markdown-it/issues/967 Release commit: https://github.com/markdown-it/markdown-it/commit/4949a10120d101bdca48bf1b13f9e790d6f2049e

This needs to be filed somewhere else:

No, that is a dev dependency. I'm talking about a warning that occurs during runtime (normal dependency.) I've just tested my idea and it works.

Before updating markdown-it:

node ..\vscode-vsce\vsce package

(node:20356) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)
 DONE  Packaged: C:\Users\RobbyBennett\Desktop\VSCodeQuickSelect\quick-select-1.0.4.vsix (8 files, 13.72KB)

After updating markdown-it:

node ..\vscode-vsce\vsce package

 DONE  Packaged: C:\Users\RobbyBennett\Desktop\VSCodeQuickSelect\quick-select-1.0.4.vsix (8 files, 13.72KB)

@joaomoreno This should be re-opened. The "somewhere else" was https://github.com/markdown-it/markdown-it/issues/967 and it's been fixed, and this repo now needs to update to markdown-it@^14 to avoid the error.

I'm getting the same error when building my project using vsce@3.0.0.

We can reproduce this issue by:

1. Installing Node 22
2. Cloning this repo
3. Installing dependencies
4. Running npm run watch:test

The tests pass but an error is logged to the console:

The fix looks like a one-liner:

$ npm i markdown-it@^14

Thanks Mark. The PR needs 2 more approvals to be merged. I suggest the collaborators of this issue to do it so the fix can be published ASAP.
