    AppData: fix `make check`
    
    The errors were:
    org.gnome.latexila.appdata.xml: FAILED:
    • tag-missing  : <name> is not present
    • tag-missing  : <summary> is not present
    • style-invalid: Too many <p> tags for a good description [5/4]
    
    I don't really like merging the two paragraphs. I think when people see
    long paragraphs they don't read them. And translations will need to be
    updated, otherwise the description will be partly in English… Oh well,
    anyway.
