Add esbuild problem matchers to auto-publish

[s-h-a-d-o-w]

• I have read the note above about PRs contributing or fixing extensions
• I have tried reaching out to the extension maintainers about publishing this extension to Open VSX (if not, please create an issue in the extension's repo using this template).
• This extension has an OSI-approved OSS license (we don't accept proprietary extensions in this repository)

Description

While I have not reached out myself, I found this: connor4312/esbuild-problem-matchers#6 (comment)

Now... it's obviously quite possible that the author simply didn't want to invest the time. And the project is MIT-licensed. I don't know how you want to handle this (I would be open to publishing a fork) but for extension developers, it sure would be nice to have this.
