ci: Adjust logic for determining build tag

This commit adjusts the logic used to determine the image tag in the build workflow. Previously, only the SHA of built ref was used, requiring image tags in manifests to be manually updated. This commit will use the 'latest' tag instead if the ref being built is on the main branch. Signed-off-by: Ryan Drew <[email protected]>
