fix: add ansible install_mode "pip3"

[rockymountainhigh1943]

This fixes an issue that was recently created by the release of a new version of the script here: https://bootstrap.pypa.io/get-pip.py.

TL;DR — they dropped support for Python2 and this now requires pip3. Maybe worth noting I may have had to manually install Python3 via SSH into the box, but I may have also already had it and it was a step I just duplicated. Either way — this fixes issues folks should be having as of this last Saturday.

Fixes #2138 - tried it out and provisioning works tickety-boo.

I had a quick play and whilst Python3.6.9 is installed, pip3 doesn't seem to exist on the base box by default.

I may be misunderstanding what you're saying, but I see the same thing. But my understanding is that pip3 gets installed by ansible when you bring the box up or do a vagrant provision. With this PR anyway. Without the PR, I suspect pip probably doesn't exist on the box either, but the provisioning pulls it down.

Ahhhh... in my previous readings I was thinking this was changing something inside the VM with the pip install that may happen as a result of Drupal VM's playbooks.

This is changing the Vagrantfile so that installs of ansible in the VM if you need it installed inside will work correctly.

Thanks for catching this!

Thank you! Provisioning works 👍

Might've misunderstood something here or in #2138 but with dev-master, I'm still seeing the following on vagrant up and vagrant provision:

ansible remote provisioner:
* The following settings shouldn't exist: install_mode

My local environment:

Vagrant 2.2.14
VirtualBox 6.1.8r137981
ansible 2.9.1
  config file = None
  configured module search path = ['/Users/jasloe/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.9/site-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.9.1 (default, Jan 30 2021, 15:51:26) [Clang 11.0.0 (clang-1100.0.33.17)]

@jasloe - Oops! Sorry about that; it should only apply for ansible_local, not ansible, so I believe the change I just pushed (see commit linked above) should fix it for those of us with Ansible running locally.
