1.45.3 breaks proxy env variables impact on `deno upgrade`

[oscar6echo]

How to replicate (Linux):

From version 1.45.2 in corp env with env variables HTTP(S)_PROXY set do deno upgrade.
It works and deno --version shows new version 1.45.3.
Do deno upgrade again and the external host is unreachable.
I infer that proxy env variables are no longer taken into account (?).

NOTE for other users:
To downgrade to 1.45.2, do curl -fsSL https://deno.land/install.sh | sh -s v1.0.0 with curl proxy env variables http(s)_proxy set.
