ci: use MavenCentral in JReleaser (#1226)

This PR updates the configuration of JReleaser to deploy the solver
using Maven Central.

1. Uses two new env var for authentication:
`JRELEASER_MAVENCENTRAL_USERNAME` and `JRELEASER_MAVENCENTRAL_PASSWORD`.
2. Updates the config according to the
[documentation](https://jreleaser.org/guide/latest/reference/deploy/maven/maven-central.html).
