shellcheck directive not taken into account

[NickDub]

Here is some of the code from my Github workflow:

- name: Apply Env Provisioning
  run: |
    # shellcheck disable=SC2086
    envsubst < ${{ inputs.provisioning-file-path }} > provisioning-replaced.yaml

and actionlint return this error:
shellcheck reported issue in this script: SC2086:info:4:29: Double quote to prevent globbing and word splitting [shellcheck]

The shellcheck directive to disable the instance is not taken into account.

It appears that this is an issue with actionlint itself: rhysd/actionlint#237
