Option to exclude/disable vscode in dump

[JtMotoX]

Would it be possible to have a brew bundle dump flag, something like --no-vscode to disable the vscode integration? I use vscode built-in sync functionality and this is causing some issues.

Currently, I have to perform sed -i '/^vscode /d' $HOME/Brewfile after every dump.

today there isn't a way to selectively output some types over others. the assumption is that if you have it installed, you will want to manage it via brew bundle -- in your case, that isn't true.

i don't know how widely used this would be but open to leaving this here to gauge the interest and welcome a PR if you want to see this land.

This has been requested in #1209 and #1212 so there are others that are interested in this option.
