🌱 Add area label lookup for prefixes to release notes tool

[g-gaston]

What this PR does / why we need it:

Building on top of @oscr's original PR (all credit to oscar), adding support to handle multiple area labels. I added the changes in a separate commit since the original PR was already reviewed. I'll squash before merge.

Adds support for release notes script to lookup area labels. If found it uses the area tag for prefix. Otherwise it uses MISSING_AREA meaning it needs manual update.
If multiple area labels are found, it uses MULTIPLE_AREAS[area1|area2...].
It also sorts each section alphabetically.

Example

> go run hack/tools/release/notes.go --from=v1.4.0

Looks good! I like the automatic sorting by area too.

Just one suggestions about using the github library instead of execcing the CLI.
