fix(wrangler): Display correct global flags in wrangler pages --help

[CarmenPopoviciu]

What this PR solves / how to test

Running wrangler pages --help will list, amongst others, the following global flags:

Some of these global flags however, such as --env, --config or --experimental-json-config, are not supported by Pages, and therefore listing them as if they were gets users confused.

This PR ensures we only list the relevant flags when running wrangler pages --help

Fixes #5725.

Before
wrangler --help

wrangler pages --help

After
wrangler --help

wrangler pages --help

wrangler pages dev --help
