Set npm constraint for gitlab-lsp
See gitlab-org/editor-extensions/gitlab-lsp#190 (comment 1861686207) for details.
This attempts to set a constraint on the version of npm packages that are allowed. We don't want to go beyond the current supported version of nodejs - this will cause Unsupported engine
errors. See https://gitlab.com/gitlab-org/editor-extensions/gitlab-lsp/-/jobs/6623002317#L195 for an example.
