Renaming the label name on Teachable Machine does not reflect immediately to the application using ml5.js.

Dear ml5 community,

I'm submitting a new issue. Please see the details below.

→ Step 1: Describe the issue 📝

Did you find a bug? Want to suggest an idea for feature?

Renaming the label name on Teachable Machine does not reflect immediately to the application using ml5.js.
The label name is stored in metadata.json which is located at https://storage.googleapis.com/, and it is cached for 3600 seconds(1 hour).
To invalidate the cache, you need to add a timestamp parameter(see the screenshots), but I found that ml5.js generates metadata URL from the model URL without passing an extra parameter.

The code is here:

ml5-library/src/ImageClassifier/index.js

Line 105 in c3123ca

const metadataUrl = `${prefix}/metadata.json`;

Can I create a PR that passes the extra parameter, if the model URL has one?
