Out Of Memory Error On Doc Gen

[ryber]

Describe the bug
When performing build-docs I get a FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

To Reproduce
Steps to reproduce the behavior:

I have placed the OpenAPI Spec here. There are two versions of it. api.yaml is the spec broken up with a bunch of external refs and merged.yaml is the same thing after I ran the redocly merge command on api.yaml

1. Given this merged.yaml file
2. Run this command with these arguments... redocly build-docs merged.yaml
3. See error: FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

Expected behavior
I get some docs :D
