Update examples to use `FeathersNumberInput` modulus feature

[Tatsuya0330]

What problem does this solve or what need does it fill?

• Implement: Modulus support for FeathersNumberInput #25265
  • It’s best to wait until this PR is merged.
• To demonstrate this feature, we should update existing examples that use HardLimit and PI.

Additional context

We should also figure out which examples could benefit from this feature: Search for HardLimit and PI :)
