Bug in 9.5.3 org--file-default-apps

[Craig STCR]

    I believe a change to the last line of org--file-default-apps
    introduced in 9.5.3 is a bug.  For example, the change prevents
    shell scripts from being recognized correctly, since the mailcap
    logic in org-file-apps-gnu is no longer included in
    org--file-default-apps.
    
    Best wishes,
