Description

• All pages are fetching all static queries, even the ones that are not being used in our monorepo Gatsby v5 project.
• This behaviour started from Gatsby v5.0.0 and is still happening on the latest release v5.11.0
• The last version with properly loaded static queries was on v4.24.0

Steps to Reproduce

Gatsby v5.11.0

1. Clone this repo and run yarn to install all the packages
2. Run yarn prod to start production server
3. Inspect the network tab to see that all static queries are being fetched for each page
4. Navigate to http://localhost:9000/_report.html to see the Perf Report

Gatsby v4.24.0

1. To see the static queries load properly in Gatsby v4 change to the branch test-gatsby-v4
2. Run yarn clean && yarn && yarn prod to restart the server.
3. If this fails delete node_modules and try again
4. Inspect the network tab or the perf report with v4 to see each page only fetches static queries that are being used by the page

Expected Result

Only the static queries that are being used on the page should be fetched.(Gatsby v4.24.0)
