chore(builder): analyze mode warning rewording

[markhoney]

The "analyze" build warning has been sitting on a screen in front of me for a while now, as I develop a site in Nuxt, and it's worded a little clumsily. Hopefully this fix is okay.

Thanks for the improved wording ☺️

Could you fix the failing tests as well (changing the message there too)?
