a9a6e9e and ea43df2 removed a step that was probably intended to work around actions/checkout#290 and actions/checkout#882, but broke the CI build if anyone used a lightweight tag (because these fetch lines actually shallow the tag depth to 1). This commit attempts to thread the needle by making this workaround conditional only to releases, where (if the person doing the release has followed the steps correctly), there is guaranteed to be an annotated tag at depth 1 in the tag history. (If I'm parsing the checkout bugs correctly, they only trigger on a tag action anyways.)
