Expected result

It should allow the filename. The linter fails on the file and recommends the same filename (_404.tsx):

./_404.tsx lint/style/useFilenamingConvention ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  ⚠ The filename trimmed as `404` should be in camelCase or kebab-case or snake_case or equal to the name of an export.

  ℹ The filename could be renamed to one of the following names:
    _404.tsx
