Improve vault login command - Setup with k3s

[faisalthaheem]

Instead of writing this command inline as "try the command vault login myroot ." it should be written with code formatting as below

vault login myroot

Notice the dot "." at the end of the current format, for someone unfamiliar with vault it's easy to mistake that part of the code.
