Fix: node:test not grouped with <BUILTIN_MODULES> (#143)

Following discussion in #142 , this adds an explicit check for
`"node:test"` to `BUILTIN_MODULES_REGEX_STR` in order to properly group
it with other builtin modules.

Test covers:
- `"node:test"` correctly gets grouped in with other builtin node
modules
- `"node:test"` is correctly sorted among other builtin node modules
- `"*node:test"` is NOT grouped in with builtin modules
- `"node:test*"` is NOT grouped in with builtin modules
- `"node"` is NOT grouped in with builtin modules
- `"test"` is NOT grouped in with builtin modules

Fixes #142
