Retrieve old configs after running the Bug report script

[yuriaps]

Is your feature request related to a problem? Please describe.

Maybe some users will not know how to set back the "old" configuration of the machine after setting up a temporary environment.

Describe the solution you'd like

I suggest including in the script OLD_HOME=${HOME}
And instructing the user to run

ZDOTDIR=${OLD_HOME} HOME=${OLD_HOME} ZIM_HOME=${OLD_HOME}/.zim

after making the report

Describe alternatives you've considered

An alternative solution is just closing and opening the terminal
