Use a venv for PC_miner.py

[wolfieboy09]

Is your feature request related to a problem? Please describe.
When installing duinocoin onto a raspi, you would usually need to break system packages for it to actually work.

Describe the solution you'd like
On the documentation, I would like the following commands to replace breaking system packages (unless you need to):
You first would have to cd duino-coin obviously.
Then you would first run these commands:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

To exit out of venv, just type the command deactivate

And because you have a venv now, you can just run source venv/bin/activate then python3 PC_Miner.py.
With this solution, you don't need to do the entire break system packages!

Describe alternatives you've considered
N/A

Additional context
I don't like to break system packages unless I REALLY need to do so.

Just a note for python3 on noble you should be simply doing:
apt-get -y install py-cpuinfo python3-colorama python3-requests python3-serial python3-psutil
