feat(richtext-lexical): more lenient url validation, URL-encode invalid urls on save (#7870)

Fixes https://github.com/payloadcms/payload/issues/7477

This simplifies validation to the point where it only errors on spaces.
Actual validation is then used in beforeChange, which then automatically
url encodes the input if it doesn't pass
