chore(ci): ignore incompatible major bumps in Dependabot config

JUnit 6 requires Java 17 and kindcontainer 2.x ships breaking changes
(drops JUnit 4, jumps to Testcontainers 2.x). Both produced PRs that
could never be merged against this project's Java 1.8 baseline, so
restrict Dependabot to minor/patch updates for these dependencies.
