Design and implement a UI to create new security advisories

[javihernandez]

Design and implement a UI that enables the creation of new AlmaLinux security advisories.

Almost all present fields will be entered manually with the following exceptions:

• The advisory ID follows the pattern ALSA-YYYY-A*** and gets incremented automatically. i.e.: ALSA-2023-A001, ALSA-2023-A002 ...
• Platform: Dropdown AlmaLinux-8 or AlmaLinux-9
• Definitive version: Automatic - I think that we can just increment this value as we make additions/updates to the advisory.
• Issued Date: Automatic
• Updated Date: Automatic
• SELF_REF: Automatic

Check ALBS Errata section to see the current information about security advisories.
