Moving discussion to forum.letta.com

[cpacker]

Hi everyone! In order to make sure that we see everyone's amazing posts / issues / feedback / suggestions, we're consolidating our forum channels to two places:

1. Our Discord (https://discord.gg/letta)
2. Our forum (https://forum.letta.com)

We're be deactivating our GitHub discussions section and are encouraging users to post on Discord or the forum instead. Please continue to open code-related issues and contributions via the issues and pull requests tabs on GitHub.

Thank you!!
