Highly outdated version, update to 1.0.14

Also Mighty Mail migrated into a single page on CurseForge. The latest version is 1.1.2 for Fabric on CurseForge: https://www.curseforge.com/minecraft/mc-mods/mighty-mail/files/all?page=1&pageSize=20&version=1.20.1&gameVersionTypeId=4

Ah, I see. I had an outdated framework mod installed too. Thank you very much.
