In the run_path function and a few other places in the entrypoint.sh shell scripts, the following errors are found by the ShellCheck linter:

In 31/apache/entrypoint.sh line 24:
    local hook_folder_path="/docker-entrypoint-hooks.d/$1"
    ^--------------------^ SC3043 (warning): In POSIX sh, 'local' is undefined.


In 31/apache/entrypoint.sh line 25:
    local return_code=0
    ^---------------^ SC3043 (warning): In POSIX sh, 'local' is undefined.

Although the script does function correctly in this state, we probably should:

• Drop the local command usage.
• Change the shell interpreter to bash.
• Suppress the warning using ShellCheck directives and call it a day.
