[2.2.x] Fixed #30385 -- Restored SearchVector(config) immutability.
Regression in 1a28dc3887e8d66d5e3ff08cf7fb0a6212b873e5.
The usage of CONCAT to allow SearchVector to deal with non-text fields
made the generated expression non-IMMUTABLE which prevents a functional
index to be created for it.
Using a combination of COALESCE and ::text makes sure the expression
preserves its immutability.
Refs #29582. Thanks Andrew Brown for the report, Nick Pope for the
review.
