feat: Update boilerplate to TLP 6.0

This changes copyright from IETF Trust to IETF Intellectual Property Management
Corporation (IPMC).

This introduces boilerplate version 6.0.

This introduces the following new `ipr` values for v3 specification:
    * `tpl202412`
    * `noModificationTpl202412`
    * `noDerivativesTpl202412`
    * `pre5378Tpl202412`

This sets `tpl202412` as the default value for `ipr` attribute.

Fixes ietf-tools#1171
