build: Bump standard to 1.25.3 from 1.1.5

Running Rubocop < 1.22.3 on Ruby v3.1 generates
`An error occurred while Layout/BlockAlignment cop was inspecting` error.
This fixes the error by bumping standard to the latest version which
also updates Rubocop version, as suggested in rubocop/rubocop#10258
