fix: restore include-component-in-tag default (false) (#888)

v3 had this option and must be configurable or at least set to `false`
so that the default behavior is to create a plain `v1.2.3` tag (without
the component name prefixed).

Found this while dogfooding our own usage of the action (in this repo).
