Remove html tags from create tag and branch translation (go-gitea#31973)

Follow go-gitea#31950 and Fix the display bug of go-gitea#31966 .

This will only fix the English version. I will update all these
translation files in crowdin after this merged so that all the languages
can be fixed.

And all these files should be backported together.

This PR remove the bold effect around the name when creating a new tag
or branch.
