ci: codify Vercel install + ignore commands

[MattIPv4]

Description

Instead of managing these in Vercel's UI only, where we recently ran into an issue of these settings being wiped/not defined as we had expected them to be, this codifies them in our repository, ensuring they're always set and any changes are properly versioned.

Validation

Schema valid.
