5202bd1 test: Bump shellcheck version to 0.8.0 (Hennadii Stepanov)

Pull request description:

  Among [added](https://github.com/koalaman/shellcheck/blob/master/CHANGELOG.md#v080---2021-11-06) rules, SC2295 could be [useful](bitcoin/bitcoin#23506 (comment)) for us.

ACKs for top commit:
  dongcarl:
    Code Review ACK 5202bd1
  fanquake:
    ACK 5202bd1 - would have rather this just been a part of #23506 to avoid another PR and pointless rebasing.
