contrib/syntax: firejail-profile.lang causes Gnome Editor to recognize every plain text document as "Firejail Profile"

[mammo0]

Description

The firejail installation also adds a language definition file in /usr/share/gtksourceview-5/language-specs/firejail-profile.lang (path on Arch Linux).
The mimetypes property contains the section text/plain. This causes for example the Gnome Editor to recognize every simple text file as a firejail profile file. See this issue: https://gitlab.gnome.org/GNOME/gnome-text-editor/-/issues/612

If I change the property line to

<property name="mimetypes">text/x-firejail-profile</property>

everything works as expected.

Steps to Reproduce

Steps to reproduce the behavior

1. Install firejail
2. Open Gnome Editor
3. type asdf and hit enter

Expected behavior

This should not change the default document type.

Actual behavior

Document type gets set to "Firejail Profile", which makes the text light up as syntax errors.

Environment

• Linux distribution and version: "Arch Linux"
• Firejail version: 0.9.72

Checklist

• The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
• I can reproduce the issue without custom modifications (e.g. globals.local).
• The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
• The profile (and redirect profile if exists) hasn't already been fixed upstream.
• I have performed a short search for similar issues (to avoid opening a duplicate).
  • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
• I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

If anyone is still facing this issue and is confused why — it's because Firejail didn't have a release since Jan 2023.
