Add "terminal pager 0" as fallback command to disable pager

[matheuskshn]

SUMMARY

In some devices, the "no terminal pager" command may be blocked due to internal security policies (as is the case in my situation). However, instead of disabling the pagination limit, I can set this limit to 0 with the "terminal pager 0" command, which achieves practically the same outcome.
