Update docs when Ubuntu 24.04 LTS releases

[HonkingGoose]

Describe the proposed change(s).

We mention specific versions of Ubuntu in our docs. We should refer to the latest LTS version.

Once Ubuntu 24.04 becomes the latest LTS, I'll go update our docs.

• [ ] Find/replace for 22.04 to 24.04
• [ ] Find/replace for Jammy or Jammy Jellyfish to Noble and Noble Numbat
• [ ] Search for ubuntu to see any remaining old references
