Warehouse: Missing translations

[NathanBnm]

Some content is still not localizable. This list compiles the missing content I noticed untranslatable. Everything is open to discussion :smile:

• [ ] Package classifiers (open discussion here #6882)
• [x] "Locale updated" banner when switching language
• [ ] Status message "All Systems Operational" in the footer (see https://github.com/pypa/warehouse/issues/7455#issuecomment-731915822)
• [ ] Size units (kB, GB etc.)
• [x] "Released: " in the package details page header
• [ ] "Our sponsors" page
• [ ] "Terms of use" and "Maintenance page" mirro as discussed in #6565

I fixed the "locale updated" flash message in https://github.com/pypa/warehouse/pull/7452.

The status message is loaded on the frontend from StatusPage so will probably not be localizable.

Some of these are due to https://github.com/pypa/warehouse/issues/6825 as well.

Status message "All Systems Operational" in the footer is translatable.

Status message "All Systems Operational" in the footer is translatable.

It's not, these strings come from an API call to an external service that happens with client-side JavaScript:
