Bump project gradle version to 0.2.4 (#38)

Following these steps from @Adriel-M to get my rule available in the
backend repo - #37

To do a release you must:
* [This PR] bump version here (after your change gets merged in):
https://github.com/Faire/faire-detekt-rules/blob/main/gradle.properties
* Run this workflow
https://github.com/Faire/faire-detekt-rules/actions/workflows/release.yml
(at this point, this is going to publish to maven central :nodders: )
* (optional but you should) git tag that commit to the same version in 1
* create a release here:
https://github.com/Faire/faire-detekt-rules/releases
* If you want to test out the rule on backend before actually creating a
release, I did create this write up in our other repo:
https://github.com/Faire/sqldelight-cockroachdb-dialect?tab=readme-ov-file#using-a-snapshot-release
