gx command

I have gone ahead and added the missing gx command.

Concerning issue:

Hi there! I see that there are 116 changed files and most of them contain formatting of them. Even if this might be a good thing to format the files, I wouldn't add such a huge change to the pull request. Could you please revert the formatting changes and leave only changes with the gx command?

[leonspohr]

Well, I agree that those formatting shouldnt be included here. But those changes were not done by me, but by ideavim bot

This is unexpected, as I understand, the actions should be explicitly enabled on forks. Anyway, to avoid such issues, I've added a condition for actions to work on JetBrains/ideavim repository.

Regarding the change: Unfortunatelly, with this change the gx command will not only open links, but also jump to the declarations or usages. This is undesired behavior, so it looks like we need some verification that we're working on the URL.
