Merge pull request #1133 from DioEgizio/bump-mac-11.0

Noticed only now that Qt 6.5 bumps the macOS requirement to macOS 11.
This was basically already effective in prism since with the Qt 6.5 bump pr macOS 10.15 user's wouldn't be able to run this, but updating the requirement here makes it more clear for the end user trying to run prism on macOS 10.15

 ## Forking/Redistributing/Custom builds policy
 
 We don't care what you do with your fork/custom build as long as you follow the terms of the [license](LICENSE) (this is a legal responsibility), and if you made code changes rather than just packaging a custom build, please do the following as a basic courtesy:
-- Make it clear that your fork is not PolyMC and is not endorsed by or affiliated with the PolyMC project (https://polymc.org).
+
-- Go through [CMakeLists.txt](CMakeLists.txt) and change PolyMC's API keys to your own or set them to empty strings (`""`) to disable them (this way the program will still compile but the functionality requiring those keys will be disabled).
+- Make it clear that your fork is not PrismLauncher and is not endorsed by or affiliated with the PrismLauncher project (<https://prismlauncher.org>).
+- Go through [CMakeLists.txt](CMakeLists.txt) and change PrismLauncher's API keys to your own or set them to empty strings (`""`) to disable them (this way the program will still compile but the functionality requiring those keys will be disabled).
 
 If you have any questions or want any clarification on the above conditions please make an issue and ask us.
 
 Be aware that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions:
- - [Microsoft Identity Platform Terms of Use](https://docs.microsoft.com/en-us/legal/microsoft-identity-platform/terms-of-use)
+
- - [CurseForge 3rd Party API Terms and Conditions](https://support.curseforge.com/en/support/solutions/articles/9000207405-curse-forge-3rd-party-api-terms-and-conditions)

 If you do not agree with these terms and conditions, then remove the associated API keys from the [CMakeLists.txt](CMakeLists.txt) file by setting them to an empty string (`""`).
