Wrap BUNDLE_GEMFILE path in quotes

[stilist]

Motivation

I store some of my projects in iCloud, so paths start with ~/Library/Mobile Documents/com~apple~CloudDocs, which has a space. Without this change, getServerVersion fails with (for example)

Error restarting the server: Command failed: BUNDLE_GEMFILE=/Users/jordancole/Library/Mobile Documents/com~apple~CloudDocs/Projects/drjohndee.net/.ruby-lsp/Gemfile bundle exec ruby -e "require 'ruby-lsp'; print RubyLsp::VERSION"
/bin/sh: Documents/com~apple~CloudDocs/Projects/drjohndee.net/.ruby-lsp/Gemfile: No such file or directory

The error shows that this is parsed as running Documents/com~apple~CloudDocs/Projects/drjohndee.net/.ruby-lsp/Gemfile with BUNDLE_GEMFILE=/Users/jordancole/Library/Mobile as an environment variable.

Implementation

I searched for BUNDLE_GEMFILE and wrapped the assignment in double quotes. It’s simplistic, but I think it's correct.

Automated Tests

I haven't added tests because I'm not sure how to implement them.

Manual Tests

mkdir -p ~/"vscode-ruby-lsp path-test"
cd ~/"vscode-ruby-lsp path-test"
echo "puts 1" > test.rb
code .

Client.getServerVersion should run without error.

I have signed the CLA!

This looks like a duplicate of #716 which may need more work on the server part.

Ah, you're right. I'll close this.
