[LINT_BUG]: non-syntactic module names causes linter to fail

[caldwellst]

box.linters version

0.10.5

Sample source code to lint

box::use(./`__tests__`)

Lint command used

lintr::lint(
  code,
  linters = lintr::linters_with_defaults(defaults = box.linters::rhino_default_linters)
)

Lint result

#> Linter 'box_unused_attached_mod_linter' failed in /lintr-test/a.R: <text>:1:4: unexpected input
#> 1: ./__
       ^

Expected result

No error should have been generated. While non-syntactic names are rare to use, this is the recommended approach for testing box modules.
