The valid test vector "bare OP_2 script is not a segwit v2 witness program" (added in #2253) is missing from the Valid PSBTs table, and its category, Input Eligibility, is not among those listed for valid PSBTs. This adds both, and renames the table's "State" column to "Category" to match the Invalid PSBTs table.
Made with my usual tools: a computer, the Internet and an LLM. The mistakes, as usual, are all mine.
