v24.06 blog post

Add the blog post for the v24.06 release.

Use some design elements from the WIP redesign already (!264 (closed)), as they look good with the beautiful header image by @dikasetyaprayogi.

Close pmaports#2606

TODO:

• update download page and listed devices for v24.06
• phosh: add 0.39.0 backports: (already done according to Newbyte, yay!)

For distros that ship phosh 0.39.0. There's a branch with fixes https://gitlab.gnome.org/World/Phosh/phosh/-/tree/phosh-0.39.x . I'll likely not tag a formal release but if you intend to put this version into a stable release cherry picking those might make sense.

• follow "release" steps from https://gitlab.com/postmarketOS/pmaports/-/issues/2819#release (partially done, some remain after merging this blog post)
