Allow the Timber\PostPreview::read_more to accept a boolean value

[gerardo-rodriguez]

Issue

The Timber\PostPreview::read_more docs say:

Set this to false to not add a "Read More" link.

But Timber\PostPreview::read_more doesn't actually accept a boolean value, it only accepts a string value type. 😬

Solution

Add bool to the readmore docblock.

Impact

Minimal to none?

Usage Changes

No usage changes, to my knowlege.

Considerations

None come to mind.

Testing

I did not add tests. Not sure how to do so.

Good catch @gerardo-rodriguez, thanks for fixing the docblock!

@timber/rangers Note for future releases, this should be revised with actual types.
