perf(gatsby-adapter-netlify): improve adapt() performance (#38988)

* test: add ssg specific headers

* fix: headers rule matching with path prefix

* test: add NODE_NO_WARNING, axios seems to use fetch now under the hood causing fetch warning on node 18 impacting some logs assertions

* perf: don't recreate headers from headerRoutes for each static route in route manifest

* test: apply NODE_NO_WARNINGS env in correct place
