Places UI Kit Samples in need of update to PlaceSearch element

[awmack]

A couple Places UI Kit samples are outdated.

Broken samples:

• ui-kit-place-search-text
• ui-kit-place-search-nearby

Updates needed:

• Replace <gmp-place-list> with <gmp-place-search> in HTML
• Replace removed methods (e.g. element.configureFromSearchByTextRequest) with the modern configuration approach.

Fortunately it looks like ui-kit-place-search-text-compact has been updated more recently and can serve as a reference!
