broken by neovim 0.7.2

[emmanueltouzery]

First off, thanks, this script is great! I really appreciate not having to depend on python.

However I think neovim 0.7.2 broke the integration. I get:

hint: Waiting for your editor to close the file... Error: Neovim must be running and have set $NVIM_LISTEN_ADDRESS for invim to communicate with it
error: There was a problem with the editor 'invim --tabedit --remote-wait'.

And this is the 0.7.2 changelog:
neovim/neovim@e8ee673

In particular, the first change is probably the cause of the issue:

BREAKING CHANGES:
neovim/neovim@fdd5178
neovim/neovim#18986 introduce $NVIM, unset $NVIM_LISTEN_ADDRESS
