Add ~/.deno/lib/ To PATH

[Maël Acier]

When installing a deno module globally, I am unable to use the exec in other steps

- run: deno install -A -n foo mod.ts

- run: foo

 /home/runner/work/_temp/013c1727-ed4e-4aa8-aca7-9e9ae2257aff.sh: line 1: foo: command not found

However it works if I add /.deno/bin/ to the PATH it works
On Linux:

- run: |
  deno install -A -n foo mod.ts
  echo "::add-path::/home/runner/.deno/bin"

- run: foo

Is it possible to add /.deno/bin/ to the PATH by default on the action?
