mock-fs is incompatible with Node v20 #592
Description
Summary
The mock-fs package is incompatible with Node v20, which causes unit tests in the aura-language-server and lightning-lsp-common to fail.
It looks like there's a draft PR in mock-fs to support Node v20 but progress seems to be slow.
A potential replacement is memfs, although there's some extra plumbing that needs to happen to make it compatible with existing tests.
Steps To Reproduce:
- Install node v20
- Run unit tests
Expected result
No test failures
Actual result
Test failures
