validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: updated to DB

bugfix: validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: need to escape the quotes in \set ... 'SALVIAS'

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `SET search_path TO public;` since this is the default

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: search_path: removed public_validations since we are not creating views

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: use psql var :datasource instead of current_schema() so that the queries are runnable without special configuration of the search_path

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `CREATE OR REPLACE VIEW` so the validations views are not unintentionally replaced when running this file

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: updated from DB
