[BUG] SELinux.fcontext_add_policy failes when using hyphen in filespec.

Description
When running the SELinux fcontext_add_policy with a filespec that contains a hyphen in the name of the directory, the state fails with
ValueError: File context for /vol/apache/dummy/bla-bla(/.*)? is not defined
While setting the fcontext with SEmanage directly works with hyphens.

Setup
Salt-master on Rocky-Linux to salt-minion on Amazon Linux 2023

Please be as specific as possible and give set-up details.

• on-prem machine
• VM (Virtualbox, KVM, etc. please specify)
• VM running on a cloud service, please be explicit and add details
  Running on latest Amazon Linux 2023 Image
• container (Kubernetes, Docker, containerd, etc. please specify)
• or a combination, please be explicit
• jails if it is FreeBSD
• classic packaging
• onedir packaging
• used bootstrap to install

Steps to Reproduce the behavior
Running the selinux state like this:

salt 'amazon2023-dev-1' selinux.fcontext_add_policy '/vol/apache/dummy/bla-bla(/.*)?' sel_type=httpd_sys_content_t
amazon2023-dev-1:
    ----------
    pid:
        24222
    retcode:
        1
    stderr:
        ValueError: File context for /vol/apache/dummy/bla-bla(/.*)? is not defined
    stdout:

Running the fcontext_get_policy returns

salt 'amazon2023-dev-1' selinux.fcontext_get_policy "/vol/apache/dummy/bla-bla(/.*)?"

    AttributeError: 'NoneType' object has no attribute 'group'

While running it directly on VM with semanage

[root@amazon2023-dev-1 apache]# semanage fcontext -a -t httpd_sys_content_t '/vol/apache/dummy/bla-bla(/.*)?'
[root@amazon2023-dev-1 apache]# semanage fcontext -l | grep bla-bla
/vol/apache/dummy/bla-bla(/.*)?                    all files          system_u:object_r:httpd_sys_content_t:s0

Expected behavior
Running the same state without hyphen

salt 'amazon2023-dev-1' selinux.fcontext_add_policy '/vol/apache/dummy/blabla(/.*)?' sel_type=httpd_sys_content_t
amazon2023-dev-1:

Additional context

My first contribution to the SaltStack community, please let me know if you need more info. Thanks!

Start in salt/modules/selinux.py, especially fcontext_get_policy at line 507 and the fcontext_add_policy path, and compare their parsing with the semanage output shown for hyphenated filespecs. Done means both functions handle the hyphenated filespec while preserving the demonstrated behavior without a hyphen.
