glim.sh: Escape key (and other non-'n' input) accepted as yes at prompts

[codemedic]

Both y/n prompts in glim.sh only check for the literal character n to mean no. Any other input — including Escape (\x1b), arrow keys, or garbage — falls through to yes and proceeds with installation.

The condition should accept only y, Y, or Enter as confirmation, and treat everything else as no.
