Different Version Derived on Gitlab vs Local

[EarthCitizen]

Nebula release plugin version 16.1.0.
Gradle version 7.5.1.

Our project is on branch release/2.0.x, branched from tag v2.0.0.

When I run ./gradlew publish final from my local machine I get:

Inferred project: fun-project, version: 2.0.1

This is the correct and expected version.

In Gitlab, I have the following settings:

GIT_FETCH_EXTRA_FLAGS: --tags --prune --prune-tags
GIT_DEPTH: "0"

This, according to the Gitlab documentation, clones the full depth of the repo, and fetches tags.

And the tags are getting pulled because I can see this in the logs:

 * [new branch]      develop               -> origin/develop
 * [new branch]      master                -> origin/master
 * [new branch]      release/2.0.x         -> origin/release/2.0.x
 * [new tag]         v2.0.0                -> v2.0.0
 * [new tag]         v2.0.0-SNAPSHOT       -> v2.0.0-SNAPSHOT

As can be seen, the tag v2.0.0 comes in with the clone. But yet, when the final task runs on Gitlab, it derives the incorrect version:

Inferred project: fun-project, version: 2.1.0

This is the incorrect version per the previous tag and the current branch name.
