  -  ----------  -----------  ---------  ----------------------------

however, if you run this and redirect the output (or try to pipe it into another process, like grep),
the output is truncated and appears to be prompting a console to use arrow keys to prompt for selection

$ openapi-generator-cli version-manager list | grep yes

this hangs.

Redirect:

$ openapi-generator-cli version-manager list >| /tmp/list.txt

also hangs.

Pipe stdin from /dev/null :

$ openapi-generator-cli version-manager list < /dev/null >| /tmp/list.txt

shows the program is expecting input, and it also does not list all versions
before it detects an EOF on input and aborts prematurely:

$ cat /tmp/list.txt

Expected behavior

When stdin or stdout is not a tty, the tool should simply run and list all versions, and not block on stdin.

Such interactive use should be a different command (select) and not just list -- a list command
should simply list the versions.

$ openapi-generator-cli version-manager list | grep yes
