Pull request overview

Updates the module’s Puppet Forge dependency constraints to allow puppet/systemd 10.x, aligning metadata.json with the intent to unblock environments/tests that already resolve newer puppet-systemd versions.

Changes:

• Expand puppet/systemd dependency upper bound from < 10.0.0 to < 11.0.0 to permit 10.x releases.

Running CI tests for this PR via #1692

[jst-cyr]

Acceptance tests are mostly green: https://github.com/puppetlabs/puppetlabs-postgresql/actions/runs/31110601439/job/92662987466?pr=1692

We are seeing failures in 4 platforms:

• Scientific 7
• CentOS 7
• OracleLinux 7
• Debian 13

None of these failures seem related to the current change in this PR. They appear to be existing issues that need to be resolved in a separate PR. Scientific 7, CentOS 7, and OracleLinux 7 appear to have been failing acceptance tests for quite some time. Debian 13 acceptance testing was introduced in late May and does not appear to have ever been fully green.

For this reason, I suggest we accept this PR as matching existing acceptance testing state.
