nixos/sysctl: use highest value on conflict for net.core.wmem_max
we previously defined a custom type for `boot.kernel.sysctl."net.core.rmem_max"`
to resolve to the highest value set. this patch adds the same behavior to
`"net.core.wmem_max"`.

as this changes the type from a string to an integer, which is a breaking
change this patch also includes a release note and updates the transmission
module to use a number for `wmem_max`.

 - Gitea 1.21 upgrade has several breaking changes, including:
   - Custom themes and other assets that were previously stored in `custom/public/*` now belong in `custom/public/assets/*`
   - New instances of Gitea using MySQL now ignore the `[database].CHARSET` config option and always use the `utf8mb4` charset, existing instances should migrate via the `gitea doctor convert` CLI command.
