.gitignore must NOT ignore .idea/ folder

[earizon]

Overview of the issue

.gitignore removes .idea from git, but .idea has been designed to be versioned and shared in .git
Only a few files inside .idea/ must not be versioned as explained in:
https://intellij-support.jetbrains.com/hc/en-us/articles/206544839-How-to-manage-projects-under-Version-Control-Systems

NOTE: idea itself add an .idea/.gitignore file, so it is quite safe to just remove .idea from .gitignore.

Motivation for or Use Case

Sharing .idea folder is a "best pattern".

Reproduce the error

Any new project inherits the .gitignore with the extra ".idea" line.

Personally, I like to ignore `.idea/` in .gitignore. Mostly because I don't expect other developers to use IntelliJ IDEA.

Me too, but I was not aware it contains stuff to be shared and I never tried it on any of my teams.

I think the same, but it doesn't hurt to have it there just in case another user uses IntelliJ. Is just a plus

The increase in the number of participants at any time and the more personalized content may have negative effects.
