vscode error: typeprof running on wrong ruby

Hi, I have a local setup using chruby (shouldn't be much different from other setups). I usually switch to the right ruby then open the project on VSCode via code ., in order to make sure that the extensions use the right ruby and deps versions. This works well for the steep plugin. However, the typeprof plugin picks up the wrong ruby, i.e. the system ruby. So, I switch to ruby 3, but I get the following error output from within vscode:

[vscode] Try to start TypeProf for IDE
[vscode] stderr: /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems.rb:283:in `find_spec_for_exe': Could not find 'bundler' (2.2.15) required by your /Users/tiago.cardoso/dev/jwt-token-kms/Gemfile.lock. (Gem::GemNotFoundException)
[vscode] stderr: To update to the latest version installed on your system, run `bundle update --bundler`.
[vscode] stderr: To install the missing version, run `gem install bundler:2.2.15`
[vscode] stderr: 	from /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems.rb:302:in `activate_bin_path'
[vscode] stderr: 	from /usr/bin/bundle:23:in `<main>'
[vscode] failed to invoke typeprof: error code 1
# that's the location from system ruby, not ruby 3

I suspect I'm entering this path, where the extensions recognizes the existence of a Gemfile, and runs typeprof via bundler, but picks up the wrong bundler. And this might be so because typeprof's not picking up the ruby defined by the VSCode ruby plugin, which I set to ruby (should have been ruby 3). steep does this a bit differently, but can't figure out what's the correct way to patch typeprof's command.

Start in vscode/src/extension.ts around lines 72-83, where the issue reports TypeProf is launched through Bundler, and compare the linked steep-vscode extension entry point. Reproduce the chruby/VSCode setup, then verify that TypeProf uses the Ruby selected before opening the project rather than the system Ruby; the reported error should no longer reference the system Ruby path.
