do not fail on inline scripts

[enspandi]

Thank you for this great addon - just what I was looking for after the popular webpack plugin didn't work ;)

Hope this fix makes sense as I got an error with an inline script (no src):

- broccoliBuilderErrorStack: TypeError: Cannot read properties of null (reading 'replace')
    at ~/my-project/node_modules/.pnpm/webpack-subresource-integrity-embroider@0.2.1/node_modules/webpack-subresource-integrity-embroider/index.js:37:44

Imo. this is mostly for catching and ignoring inline scripts. Having a link element without a href attribute doesn't sound very useful.

But in both cases I think it's safe to ignore integrity hash calculation...

Looks good to me.

Do you mind adding another test app, which covers the scenario of inline scripts?

[enspandi]

The test app is like the default one - just this part is different

@enspandi Lockfile seems to be out of sync.

Thanks a lot!
