[Package Update]: Many lts and rc kernel packages extremely out of date

### Package Name

linux-cachyos-lts-* linux-cachyos-rc-*

### Repository

cachyos

### Current Version

6.12.x 6.19.x 7.0.x

### Requested Version

Current

### Upstream Release URL

kernel.org

### Additional Notes

A good many rc and lts kernel packages have not been updated for months.

( server and cacule kernel packages also exist and have not seen updates since 2025 and 2023 respectively. These seem even more esoteric though. )

See for example https://packages.cachyos.org/?current_page=3&page_size=100&search=linux-cachyos

https://packages.cachyos.org/?current_page=4&page_size=100&search=linux-cachyos

Affects all repos.

As per usual with these - if there are some we should drop instead then that makes sense too. Otherwise they should probably be updated.

Start with the linux-cachyos package listings linked in the issue and compare the lts and rc versions against the current releases on kernel.org. Determine which affected packages across all repositories should be updated or dropped, then verify the package listings show current versions or that removed packages are no longer offered.
