Implement transition:persist-props

[matthewp]

Changes

• Implements transition:persist-props as explained in https://github.com/withastro/astro/pull/10136
• This is a simple transformation to data-astro-transition-persist-props with the same value.
  • Very similar to how transition:persist works.
• This means for dynamic use-cases users can use the data- attribute instead.

Testing

• New test case added

@martrapp It's renamed in the transform step, so it doesn't exist when it gets to the printer and doesn't need to be skipped.

Thought it would be the same for transition:persist but then I saw that there is one case were we append. ✔️
