Algebraic_foundations: unknown group in documentation

[albert-github]

Analogous to the issues #7691, #7692 and #7693 adding a warning to doxygen gives me the warning

Algebraic_foundations/doc/Algebraic_foundations/Concepts/ExplicitInteroperable.h:26: warning: Found non-existing group 'PkgAlgebraicFoundationsInteroperabilityConcepts' for the command '@ingroup', ignoring comm
and
Algebraic_foundations/doc/Algebraic_foundations/Concepts/Fraction.h:16: warning: Found non-existing group 'PkgAlgebraicFoundationsFractionsConcepts' for the command '@ingroup', ignoring command
Algebraic_foundations/doc/Algebraic_foundations/Concepts/FromDoubleConstructible.h:14: warning: Found non-existing group 'PkgAlgebraicFoundationsConcepts' for the command '@ingroup', ignoring command
Algebraic_foundations/doc/Algebraic_foundations/Concepts/FromIntConstructible.h:17: warning: Found non-existing group 'PkgAlgebraicFoundationsConcepts' for the command '@ingroup', ignoring command
Algebraic_foundations/doc/Algebraic_foundations/Concepts/ImplicitInteroperable.h:28: warning: Found non-existing group 'PkgAlgebraicFoundationsInteroperabilityConcepts' for the command '@ingroup', ignoring command

• where do these \ingroup belong to or should the lines be removed?
