ci: Bump runner size for extension CLI publishing job (#52433)
Finn Evers
created
As of https://github.com/zed-industries/zed/pull/50750, the runner size
for building the extension CLI is no longer sufficient due to the
addition of the `settings_content` crate as a dependency. The [most
recent workflow
run](https://github.com/zed-industries/zed/actions/runs/23554506504/job/68577404831)
fails while building that crate due to insufficient RAM availlable
during the build.
Removing the dependency is not an option, as we do want to have the
validation here and need structs from the settings content crate to do
so.
Thus, changing the job here to a larger runner to fix the build and also
build it faster.
