Title padding does not appear to be scriptable (or type needs updating?)

### Documentation Is:

- [ ] Missing or needed?
- [ ] Confusing
- [x] Not sure?

### Please Explain in Detail...

The configuration section (https://www.chartjs.org/docs/latest/configuration/title.html#title-configuration) indicates that the `padding` property is scriptable, but the allowed types include only `number | { top: number; bottom: number }` and not `Scriptable` or `ScriptableOptions`, etc: https://github.com/chartjs/Chart.js/blob/ec927ee0854b7369b892afbdb14d5a12196887de/src/types/index.d.ts#L2543

### Your Proposal for Changes

It appears that either:
- The documentation needs to be updated to show that `padding` on the `Title` element is not scriptable
- Or if it is scriptable, the types may need to be edited to include functions that return `number | { top: number; bottom: number }`

### Example

_No response_

Compare the title configuration documentation at the linked padding section with the declaration in src/types/index.d.ts around line 2543. Determine whether Title padding is scriptable, then align the documentation or type definition so they agree. Done means the documented behavior and allowed type are consistent.
