ci: make internal+promote release higher priority in runtypes (#64049)

With the https://github.com/sourcegraph/sourcegraph/pull/63985/files
PatchRelease is matched before InternalRelease leading to the wrong
build being generated.

We therefore move the Promote and Internal Release runtypes higher in
priority so that they get matched first.

## Test plan
```
export RELEASE_INTERNAL=true
export VERSION="5.5.2463"
go run ./dev/sg ci preview
```
👇🏼 
```
go run ./dev/sg ci preview
⚠️ Running sg with a dev build, following flags have different default value unless explictly set: skip-auto-update, disable-analytics
If the current branch were to be pushed, the following pipeline would be run:
