[Bug] wxGUI Interactive Python Shell: help(gs) and AddLayer() failing

[neteler]

Describe the bug

The Python tab offers

Welcome to wxGUI Interactive Python Shell 0.9.8

Type "help(gs)" for more GRASS scripting related information.
Type "AddLayer()" to add raster or vector to the layer tree.

However, both commands fail:

>>> help(gs)
None

and

>>> AddLayer()
Traceback (most recent call last):
  File "/usr/lib64/python3.9/code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>
TypeError: AddLayer() missing 1 required positional argument: 'name'

Of course this works (demolocation):

AddLayer('country_boundaries')
Vector map <country_boundaries@PERMANENT> added

Expected behavior

• help(gs) should do something useful
• Type "AddLayer()" to add raster or vector to the layer tree. might be rephrased to e.g.
  • Type "AddLayer('mapname')" to add raster or vector to the layer tree.

Note that help(grass) prints None also in GRASS GIS 7.8.
