Description

#467 increased the default length of the commit hash created by the sha directive

This was released in v5.6.0 which made it immediately apply to everyone whose workflow specified release v5 in their actions.

This change unfortunately broke my workflows, because other parts of our workflows were hard-coded to match the size of the tags created by this action.

Please consider pulling this release and re-releasing it as v6.

Expected behaviour

v5 creates short "sha" tags with 7-character commit hash

Actual behaviour

v5 suddenly creates short "sha" tags with 12-character commit hash
