gh: update to 2.72.0

2.72.0

This release marks the public preview of several accessibility
improvements to the GitHub CLI that have been under development over the
past year in partnership with our friends at Charm including:

- customizable and contrasting colors
- non-interactive user input prompting
- text-based spinners

These new experiences are captured in a new gh a11y help topic command,
which goes into greater detail into the motivation behind each of them
as well as opt-in configuration settings / environment variables.

2.71.0

- gh pr create: Support Git's @{push} revision syntax for determining
  head ref
- Introduce option to opt-out of spinners
- Update configuration support for accessible colors
- gh config: add config settings for accessible prompter and disabling
  spinner

2.70.0

This release contains dark shipped changes that are part of a larger
GitHub CLI accessibility preview still under development. More
information about these will be announced later this month including
various channels to work with GitHub and GitHub CLI maintainers on
shaping these experiences.

2.69.0

  characters
