GAP v0.5.0

Diff since v0.4.4

Summary of changes

From the user's viewpoint, this release mainly provides better support for Julia's constructors (compared to the function gap_to_julia),
and iteration for GP lists.
From a technical viewpoint, the most important changes are that now GAP_jll is used, and that GitHub Actions are used instead of Travis.

The following changes are in GAP 0.4.0:

• Add GAP.prompt() function which gives a GAP prompt inside Julia
• Add support for Julia keyword arguments on the GAP side

  idiomatic Julia code accessing GAP objects

  which can save time and disk space when rebuilding or reinstalling GAP.jl

  OSCAR do
• Remove the implicit dependency on LinearAlgebra.jl
