Bots use pronouns (#91483)

## About The Pull Request

Makes bots use pronouns if they're given them.

## Why It's Good For The Game

Most bots are genderless, which is a given. But notably the hygiene and
sec bots use he/him instead of it/its, the tooltips related to their
panel and such didn't adhere to this until now. If a bot is given
gender, the description, tooltips and all other text info should adhere.

## Changelog
