Backport #8604 to Wrangler v3 (#8662)

* Amend `pages dev` error message when an environment is requested

if users run `wrangler pages dev --env=my-env` they currently get
an error saying to use `--branch` instead, the `--branch` option
however only applies to `wrangler pages deploy`, so this error
message can easily confuse users, the changes here update the
error message to simply state that `--env` is not available for
local development

* fixup! Amend `pages dev` error message when an environment is requested

fix formatting
