Remove signature to allow any table name for from

[olee]

I think the 3rd signature for the from method should be removed which currently allows using any table name inside the postgrest client:

postgrest-js/src/PostgrestClient.ts

Lines 59 to 66 in f730aa7

	from<
	TableName extends string & keyof Schema['Tables'],
	Table extends Schema['Tables'][TableName]
	>(relation: TableName): PostgrestQueryBuilder<Schema, Table, TableName>
	from<ViewName extends string & keyof Schema['Views'], View extends Schema['Views'][ViewName]>(
	relation: ViewName
	): PostgrestQueryBuilder<Schema, View, ViewName>
	from(relation: string): PostgrestQueryBuilder<Schema, any, any>

Currently this makes it quite hard to catch errors when for example removing or renaming tables.

If anyone would like to allow calling from on unknown tables, they could still do it imho by adding an index signature to the schema eg.

type Database = {
    public: {
        Tables: {
            /* standard signatures go here */

            // Allow any table name in from etc
            [key: string]: any;
        }
    }
}
