## About The Pull Request

OpenDream is adding support for proc and var typechecking using `as` in
https://github.com/OpenDreamProject/OpenDream/pull/1705

BYOND silently ignores most uses of `as`, but OpenDream can leverage it
for static typing.

E.g. the following code will error in OpenDream while doing nothing in
BYOND:
```
/datum/proc/meep() as text
    return "meep"

/datum/foobar/meep()
    return 5
```
`Warning OD2701 at code.dm:29:8: /datum/foobar/meep(): Invalid return
type "num", expected "text"`

Pragmas allow these type emissions to be warnings, errors, or suppressed
entirely.

This PR modifies some existing uses of `as` in TG to prevent
`ImplicitNullType` warnings (which is when a var with a null value
doesn't explicitly have the `|null` type specified). This specific
pragma is a bit opinionated so it could simply be disabled, but since
this has no impact on BYOND behavior I don't see a reason not to fix
these examples anyways.

## Why It's Good For The Game

Typechecking.
