SC2183: Flags applied to %()T makes shellcheck report missing variables

[AustralEpitech]

For bugs with existing features

• Rule Id (if any, e.g. SC1000): SC2183
• My shellcheck version (shellcheck --version or "online"): 0.11.0
• The rule's wiki page does not already cover this (e.g. https://shellcheck.net/wiki/SC2086)
• I tried on https://www.shellcheck.net/ and verified that this is still a problem on the latest commit

Here's a snippet or screenshot that shows the problem:

#!/bin/bash
printf '%.4(%H:%M)T' -1

Here's what shellcheck currently says:

Line 2:
printf '%.4(%H:%M)T' -1
       ^-- SC2183 (warning): This format string has 3 variables, but is passed 1 argument.

Here's what I wanted or expected to see:
