Attempt to allow Draupnir to use room V12. (#918)

- Updated to matrix-basic-types 1.4.0 which changes
  the regex validating room ids.

- Changed the package override so that all dependencies
  use matrix-basic-types 1.4.0, including the matrix-protection-suite.

- Removed code that tries to store details about discovered rooms in
  the room takdedown protection. These were unreliable for so many
  reasons and also are now broken given the room origin cannot be
  extracted from the room id. Details for why this is can be found in
  the reviews of
  matrix-org/matrix-spec-proposals#4291.
