Improve in-game translations

[Tiagoquix]

• [x] My code follows the code style of this project.
• [x] I have read the CONTRIBUTING document.

Issue type: bug fix (non-breaking change which fixes an issue).

This pull request:

• includes miscellaneous changes to improve the translations here and there (including English);
• adds some format strings that are missing from certain languages;
• changes some instances of "client" to "player" in the English translations;
• removes the format string from the sourcesleuth_kicktext string (from sbpp_sleuth.phrases.txt) as it does not seem to be necessary;
• copies the translations from the Ban Not Verified string (from sbpp_main.phrases.txt) to the Player Comms Not Verified string (from sbpp_comms.phrases.txt) since they are the same string and the sbpp_main's string has more translations.
• improves the Brazilian Portuguese translations.

Hello,

Thanks for the PR. Please rebase it onto the php81 branch.

I will do another PR as it will be easier both for me and for you.
