Fixes an issue in the CI job lint that we've recently encountered in PRs (325366d).

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

To test:

• Check that all CI jobs pass.

PR submission checklist:

• I have considered adding unit tests where possible.
• I have considered if this change warrants user-facing release notes more info and have added them to RELEASE-NOTES.txt if necessary.

In the future, we could set this option directly in the Docker image.
