[lldb-dap] Update npm dependencies (llvm#125832)

This commit upgrades our npm dependencies to the latest available
version.

I was prompted to this change because `npm run package` failed for me
with an error. The error disappeared after upgrading `@vscode/vsce`. I
also upgraded the other dependencies because I think it's generally
preferable to stay up-to-date.

I did not bump the `@types/vscode` and `@types/node` versions, since
this would effectively make older VS-Code versions unsupported. I also
changed `@types/vscode` to be a precise version match, since we are
claiming compatibility with that version via the `enginges.vscode`
property.
