Remove isLarge prop from Button block in FSE starter-page-templates

[andrewserong]

In Gutenberg the isLarge prop was removed from the Button component in WordPress/gutenberg#23239 — this PR removes the prop from our instance of the Button block in starter page templates, so that it doesn't error in the console

This it the button in question — it should look the same after applying this change.
