Remove Ctrl + 1, 2, 3, 4, 5 shortcuts

[andycraig]

Fixes #368

What problem did you solve?

Shortcuts Ctrl + 1, 2, 3, 4, 5 overlap with default VS Code shortcuts. This PR removes these shortcuts. The commands are unchanged.

How can I check this pull request?

Run command Preferences: Open Keyboard Shortcuts and search for Ctrl + 1. Observe that only command is workbench.action.focusFirstEditorGroup.

I just removed the shortcuts lines but I should have removed the whole command JSON section. Will update and force push.

Fixed and ready for review.

LGTM.

Do we consider this as breaking changes? Users who rely on these shortcuts as defaults will suddenly find that they don't work anymore. We might need strong notice in the changelog.

@renkun-ken Yes, We can move the old shortcut to the wiki and put the URL on the CHANGELOG

[renkun-ken]

@andycraig Would you like to update the wiki and changelog as @Ikuyadeu suggests?

[andycraig]

@renkun-ken Yep, will do so this weekend.

[andycraig]

Unlikely to get to it this weekend after all, but it's on my list.

[andycraig]

Done! @Ikuyadeu @renkun-ken Could one of you check the update to the CHANGELOG? If you are happy with it, please merge.

Thanks!

[renkun-ken]

It looks perfect! Thanks!
