Laminas mail expects a value in the format "type/subtype"; received "image/*"

Issue detected when using GLPI Mailgate https://github.com/glpi-project/glpi/issues/8375 to get messages with attached files "image/*"

To fix this issue, the RegEx at the file "laminas-mail/src/Header/ContentType.php", line 114 should be changed to

/^[a-z-]+/[/*a-z0-9.+-]+$/i
