Our CLI's user agent is reported as undefined/undefined. This is because we are reading the package name and version from the CLI's package.json by using a relative path to the source file (using __dirname). However, since a good long while, our production CLI is being bundled using esbuild into a single JavaScript file. This means that at runtime, __dirname points to a completely different directory than the one it's been coded against, and so reading the package.json fails.

Account for this by using a function that searches for package.json; still do it defensively so that if some other condition we didn't predict causes the search to fail, our CLI doesn't fail.

It should not be possible, but I'm seeing `undefined/undefined` as the
user agent in CloudTrail logs, and it looks like it is the CLI causing
this.

Add a test (which succeeds) and some fallback behavior to help
and debug this some more if we see it again in the future.
