Fix lint errors using deno lint --fix

[taras]

Motivation

#905 is blocked because of lint errors, so I will fix them here and then rebase.

Approach

1. Ran deno lint --fix
2. Using npm:process instead of globalThis.process
3. Pinned to 1.46.x in CI

Might have been caused by the Deno default linting rules changing in between point releases of Deno. We may want to pin our Dino version in the set up Dino action so that this doesn't happen in the future.

@cowboyd I'll do this in a separate PR. I'll do it here.
