Incomplete `$PATH` for `:!` command

Describe the bug
Any command run with the :! <shell-command command seems to run with a very basic PATH set:

To Reproduce
Simply type:

:%!echo $PATH

in an empty file to see the $PATH. For me, it is just /usr/bin:/bin:/usr/sbin:/sbin. This is not enough to pick up executables installed somewhere else (like with homebrew on mac for example, I have jq installed to /usr/local/bin/jq, which is not picked up).

:%!jq .

with jq installed to /usr/local/bin should json pretty-print the current file with jq as an example. Note that

:%!/usr/local/bin/jq .

actually works

Expected behavior
%:! <shell-command> should pick-up commands from /usr/local/bin too.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.21.7
• VSCode version: Version: 1.60.0 (Universal)
• OS: Mac OS Big Sur 11.4 (20F71)

Additional context
Is this maybe somehow configurable through vscode settings? I was digging through the code and it seems like !: is just using child_process.exec...

Start in src/util/externalCommand.ts around line 88, where the issue identifies child_process.exec as the implementation for :! commands. Reproduce with :%!echo $PATH and :%!jq ., then verify that commands installed in /usr/local/bin are found without using an absolute path.
