fix(garden): remove trailing slashes from openplantbook api urls and update label

Trailing slashes on /plant/search/ and /plant/detail/ caused Django to
return an HTML redirect page instead of JSON. SDK uses no trailing slashes.

Also updates the helper text to reference OpenPlantBook instead of Perenual.
