Hello all, please see #72.

[KaiSchwarz-cnic]

with npm 8++, you can rely on an "overrides" section to override package versions explicitely.

"overrides": {
    "semantic-release": "^19.0.3"
}

of course to be seen as temporary solution until a replacement for maven-semantic-release is available or a new maintainer.
