docs: list ProMicro solo build, document CARDKB_I2C, update release notes

- README's env table and external_keyboard.md's device-support table both
  get a ProMicro row -- missed when the PR #31 merge landed since neither
  was in scope for that commit.
- external_keyboard.md and build_flags.md now cover CARDKB_I2C alongside
  ENV_PIN_SDA/ENV_PIN_SCL: the PR generalised CardKB bus selection to a
  single macro after build_flags.md was first written, so the doc only had
  the older (still valid, but no longer the only) form.
- release-notes.md: added the ProMicro solo build and the new Build Flags
  reference page to v1.26's What's New.
