The layout on the review code view was broken depending on length of the text. Change all three buttons to icons with tooltip to make more space for these long texts.
Fixes: #20922
* Refactor `i18n` to `locale`
- Currently we're using the `i18n` variable naming for the `locale`
struct. This contains locale's specific information and cannot be used
for general i18n purpose, therefore refactoring it to `locale` makes
more sense.

* Update routers/install/install.go
* Add whitespace handling to PR-comparsion
In a PR we have to keep an eye on a lot of different things. But sometimes the
bare code is the key-thing we want to care about and just don't want to care
about fixed indention on some places. Especially if we follow the pathfinder
rule we face a lot of these situations because these changes don't break the
code in many languages but improve the readability a lot.
So this change introduce a fine graned button to adjust the way how the
reviewer want to see whitespace-changes within the code.
The possibilities reflect the possibilities from git itself except of the
`--ignore-blank-lines` flag because that one is also handled by `-b` and is
really rare.
