chore: collect --dry-run and --yes opts info in feature request template

[SteveLauC]

What does this PR do

Collection the following information in the feature request template so that we don't need to ask.

* Does it have a `--dry-run` option? i.e., print what should be done and exit
* Does it need the user to confirm the execution? And does it provide a `--yes`
  option to skip this step?

Standards checklist

• The PR title is descriptive.
• I have read CONTRIBUTING.md
• Optional: I have tested the code myself

For new steps

• Optional: Topgrade skips this step where needed
• Optional: The --dry-run option works with this step
• Optional: The --yes option works with this step if it is supported by
  the underlying command

If you developed a feature or a bug fix for someone else and you do not have the
means to test it, please tag this person here.
