fix(bash-ide-vscode): switch to pnpm

[shyguyCreate]

• 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

This PR fixes should fix the outdated extension mads-hartmann.bash-ide-vscode by changing the dependency to pnpm that was changed in this commit.

Decided to check the issue in my forked repo, now I do not know the source of the error. (workflow here)

EDIT: I understand the error now, it is hard to get, but this PR should be ready now.
