[Doc] Document the default for reset_angle in the Motor class doc

[BertLindeman]

Describe the issue
In #389 the argument reset_angle has been introduced.
The doc does not state whether True or False is used if the argument is not specified.

Suggested improvement
After

reset_angle ([bool](https://beta.pybricks.com/static/docs/v2.19.0/micropython/builtins.html#ubuiltins.bool)) 
– Choose True to reset the rotation sensor value to the absolute marker angle (between -180 and 179). 
Choose False to keep the current value, so your program knows where it left off last time.

add

If `reset_angle` is not specified, `False` is used.

Or better fitting text.

This came up in #1916

[EDIT] If I knew how / where I would have tried a PR.
[EDIT 2] Simple? in the doc Will try there.

I do no want to stir up too much for this.
Looking in pupdevices.py

Is the policy to document the defaults in the parameter list:

This would seem to me that the default for reset_angle would be True.

Tested with

from pybricks.pupdevices import Motor
from pybricks.parameters import Port
from pybricks import version

print(version)

motor = Motor(Port.A)
print("start at", motor.angle())

('technichub', '3.6.0b2', 'ci-build-3607-v3.6.0b2-19-g9e5ef68d on 2024-10-29')
start at -146
('technichub', '3.6.0b2', 'ci-build-3607-v3.6.0b2-19-g9e5ef68d on 2024-10-29')
start at -146

Re-reading shows me I do not understand this mechanism at all.

The difference between reset_angle=True scales the motor angle between -180 and 179,
reset_angle=False keeps the motor angle even if it is outside that range.

So closing this as stupid.
