fix: Use --block option for Kate editor in translations

[DKindeev]

This fixes the kate command, needs to use "kate -b".

@DKindeev thank you for contributing this fix! I cannot really validate whether it is correct unless I repeat the entire research you have already done, which kind of defeats your research. Maybe it would make more sense to accompany the PR description with a pointer to Kate's documentation?

Additionally, the PR modifies a generated file:

git-scm.com/external/book/content/book/az/v2/Appendix-C:-Git-Əmrləri-Quraşdırma-və-Konfiqurasiya.html

Line 2 in 107cf93

### DO NOT EDIT! Generated by script/update-book2.rb

Which means the next time this file is generated, your edit would be gone! So where to contribute the fix instead? The answer lies here:

In other words: Please open a new PR at https://github.com/progit2-aze/progit2 and accompany the PR with a description that makes it easy to verify that the change is correct. Thank you!

Thank you. I needed to change that in another repo.

I think this is the line you want to change: https://github.com/progit2-aze/progit2/blob/9f5e87d19b622e05fd9f7cc215bcd39c79d5995b/C-git-commands.asc?plain=1#L51

No, I actually wanted to fix russian version of documentation. I have already opened a pr in the correct repo, but it is still hanging. Could you please review it?

progit/progit2-ru#479 - here it is.
