[Bug]: @bazel/runfiles should not throw an exception if used outside of a Bazel invocation

[shs96c]

What happened?

I have a library that sometimes expects to be used in a Bazel build, but can also be used in a regular JS project built using npm. One utility function attempts to locate files, using @bazel/runfiles if it can't find the files the regular way.

When used in the regular npm project, the line const { runfiles } = require('@bazel/runfiles') throws an exception. I would expect the check to be done when the resolve function is called, allowing @bazel/runfiles to be used as a regular library in a normal JS project.

Version

Bazel 7.2.1.
Runfiles 5.8.1

How to reproduce

Load `const { runfiles } = require('@bazel/runfiles')` in a regular project

Any other information?
