devbox shell and devbox shell --pure have differences in inheriting the host shell's env variables. But there is no devbox-defined env variable for users and devbox itself to know if it is in a pure shell or regular shell.
This PR sets a DEVBOX_PURE_SHELL=1 env variable to help fix that issue.
This will allow users to differentiate and customize their setup based on if they're in a pure shell or not. For example, not sourcing .bashrc if in a pure shell.
How was it tested?
devbox run build
devbox shell then env | grep "DEVBOX_PURE_SHELL"
exit
devbox shell --pure then env | grep "DEVBOX_PURE_SHELL"
confirm the env variable is set for pure shell and not for regular shell.
