GHAS/CodeQL reporting missing input sanitization

[automartin5000]

I posted this in the AWS SDK repo, but thought I should repost here since this seems to be the source.

This code has started triggering a CodeQL finding for us.

Specifically, it's this line of code:

part = `"${part.replace(/"/g, '\\"')}"`;

The full security notification is:

Incomplete string escaping or encoding - This does not escape backslash characters in the input.

See for aws/aws-sdk-js-v3#6623 answer. The CodeQL maintainer recommended dismissing the false positive.
