python3 command is just python sometimes

[BinaryBrain]

Summary
On Archlinux and some other OS (maybe Windows as well?), python 3.x is ran using the python command and python 2.x using the python2 command. Here, we're assuming it's always python3:

Parsr/server/src/modules/TableDetectionModule/TableDetectionModule.ts

Line 35 in dc3bec7

const tableExtractor = child_process.spawnSync('python3', [

Steps To Reproduce
Steps to reproduce the behavior:

1. Have your path with python pointing on Python 3.x
2. Remove python3 from your path.

Expected behavior
Table extraction should run.

Actual behavior
A node error: Error: spawnSync python3 ENOENT.

Environment

• Reference commit/version: dc3bec7ae62b0db12a075f31c26ba8951a63c2f7
• Other platform details: Python 3.x is just python, not python3
• OS: Arch Linux, maybe others?

I'm unsure but we may have the same issue on the Docker container.

Commit 387707b should resolve this but the docker container still needs a look.
