Update .editorconfig to match the new one from the OpenRA repository

[oldnaari]

Recently my mod began to refuse to pass the CI. Copying the .editorconfig from https://github.com/OpenRA/OpenRA/blob/bleed/.editorconfig was an important component for fixing that. So here it comes )

Hi there and thanks for the PR.
I already had a commit for the .editorconfig file in #193, but I don't mind dropping that in favor of this PR.
However, you seem to have copied the file from OpenRA's bleed branch, which is about 10 commits ahead of release-20231010.
Currently the ModSDK has a single master branch that targets OpenRA releases and very rarely gets patches inbetween. I'd say you should either take the release version of the file and we merge this before #193 or you wait for that to get merged and then this can be merged as an inbetween-releases patch.

Hello @penev92. My bad didn't see the pull request. I will better wait for #193 in that case

#193 was merged so you can rebase this.

I think we can close this pull request for now. What I wanted to achieve here is done by #193 in a more thoughtful manner.
