vscode error: typeprof running on wrong ruby

从 vscode/src/extension.ts 第72-83行附近开始，这里 issue 报告了 TypeProf 是通过 Bundler 启动的，并与链接的 steep-vscode 扩展入口点进行比较。复现 chruby/VSCode 设置，然后验证 TypeProf 使用的是打开项目之前选择的 Ruby，而不是系统 Ruby；报告的错误不应再引用系统 Ruby 路径。

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.
