Bug located in booleans.py

🤓 Before submitting the issue

• I have visited the Troubleshooting section.
• I have searched among the existing issues.
• I am using a Python virtual environment.
• I am using the latest version of PyMAPDL and its dependencies (fully updated virtual environment). You can update them using pip install --upgrade --upgrade-strategy eager ansys-mapdl-core.

🔍 Description of the bug

mapdl.asbl() seems to have a small bug in it's definition.
When issuing the command in pyansys and specifying that the initial area is to be deleted (keepa="DELETE"), the initial area is not deleted.
Workaround with specifing default values with BOPTN [ mapdl.boptn(value="NO") ] beforehand gets the job done.

When checking out the defintion of the asbl command, I think the error is in line 427 of file booleans.py (ansys-mapdl-core version 0.65.2)

Implementation is:

command = f"ASBL,{na},{nl},{keepa},{keepl}"

which should - according to my understanding - have an aditional komma before {keepa}:

command = f"ASBL,{na},{nl},,{keepa},{keepl}"

For reference, the APDL ASBL Command definition is:
ASBL, NA, NL, --, KEEPA, KEEPL
which has this blank space inbetween to presumably keep the format of for example the ASBA command that has the additional SEPO as a key:
ASBA, NA, NL, SEPO, KEEPA, KEEPL

The corresponding MAPDL Code would be for example:
FINISH
/CLEAR,NOSTART
/PREP7
k,1,0,0
k,2,0,1
k,3,1,1
k,4,1,0
a,1,2,3,4
l,1,3
asbl,1,5,,delete,keep

🕵️ Steps To Reproduce

#Minimum working example
from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl()

mapdl.prep7()
mapdl.k(1,0,0)
mapdl.k(2,1,0)
mapdl.k(3,1,1)
mapdl.k(4,0,1)
area_no = mapdl.a(1,2,3,4)
line_no = mapdl.l(1,3)

# mapdl.boptn(value="NO") # if issued, initial area is deleted

mapdl.asbl(na=area_no,nl=line_no,keepa="DELETE",keepl="KEEP") # keepa="delete" but area is still kept

mapdl.open_gui() # for visualization

mapdl.exit()
