release_version: Do not use prerelease field (#43669)

- **release_channel: Do not use prerelease channel for build id**
Prerelease channel specifiers always compare as less than to
non-prerelease, which led to 2 auto-update bugs fixed in
https://github.com/zed-industries/zed/pull/43595 and
https://github.com/zed-industries/zed/pull/43611.
We'll use a dot-delimited build specifiers in form:
release-channel.build_number.sha1 instead
- **auto_update: Do not display full build metadata in update
notification**

Release Notes:

- N/A
