Content

This PR replace Bots with bots to help translators choose an existing translation, if any. Please note that localized keys are case sensitive on Weblate:

• https://translate.element.io/translate/element-web/matrix-react-sdk/en/?checksum=da6abfa2f95bf3c
• https://translate.element.io/translate/element-android/element-app/en/?checksum=87ef32a0d2e7c642

Create a Weblate account to see the difference, if you do not have one yet.

Motivation and context

1. Let translators reuse an existing translation, if any
2. Make translation consistent among projects
