Dean Sheather e5c8c9bdaf chore: pin dogfood to release branch during release freeze (#20028)
Relates to https://github.com/coder/dogfood/pull/189
Closes https://github.com/coder/internal/issues/1021

- Adds new script `scripts/should_deploy.sh` which implements the
algorithm in the linked issue
- Changes the `ci.yaml` workflow to run on release branches
- Moves the deployment steps out of `ci.yaml` into a new workflow
`deploy.yaml` for concurrency limiting purposes
- Changes the behavior of image tag pushing slightly:
    - Versioned tags will no longer have a `main-` prefix
    - `main` branch will still push the `main` and `latest` tags
    - `release/x.y` branches will now push `release-x.y` tags
- The deploy job will exit early if `should_deploy.sh` returns false
- The deploy job will now retag whatever image it's about to deploy as
`dogfood`

# This script prints the image tag to use for the given arch and version
# combination.
#
# Usage: ./image_tag.sh [--arch amd64] [--version 1.2.3]
#
# The --arch parameter accepts a Golang arch specification. If not specified,
# the image tag for the multi-arch image will be returned instead.
#
# If no version is specified, defaults to the version from ./version.sh. If the
# supplied version is "latest", no `v` prefix will be added to the tag.
#
# The returned tag will be sanitized to remove invalid characters like the plus
# sign.
