Using `pipx ensurepath` adds the pipx install directory to $PATH.

On v1.2.0 (the current version we pin) it does it in the following way:

1. BEGIN pipx config

1. pipx will install binaries to "~/.local/bin"

export PATH="/opt/undodb5/bin:/opt/cmake/bin:/opt/rtags-2.38/bin:/opt/undodb5/bin:/opt/cmake/bin:/opt/rtags-2.38/bin:/opt/undodb5/bin:/opt/cmake/bin:/opt/rtags-2.38/bin:/home/ubuntu/.rbenv/bin:/home/ubuntu/.local/bin:/home/ubuntu/.rbenv/bin:/home/ubuntu/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/ubuntu/cli_bin:/home/ubuntu/cli_bin:/home/ubuntu/cli_bin:/home/ubuntu/.local/bin:/home/ubuntu/.local/bin"

1. END pipx config

This overwrites the whole path, this is bad.

On v1.4.3 it fixes this to append to the PATH like the following:

 # Created by `pipx` on 2024-02-16 19:00:20 37 export PATH="$PATH:/home/ubuntu/.local/bin"
