[wrangler]: Fix local mode force on pages dev

[Skye-31]

Fixes N/A - Found in the Discord

What this PR solves / how to test: Pages dev previously forced people to use local mode, however this got broken somewhere in the past. This pull fixes it, and prevents people from using remote mode once again

TLDR; Force local was incorrectly put in the startApiDev version of unstable_dev instead of the one that Pages uses
