fix: bump paper handlebars to 5.10.4

[huntario]

What? Why?

Bump paper handlebars to remove quotes from nonce handlebars helper - bigcommerce/paper-handlebars#309

How was it tested?

1. Pull PR locally
2. Within directory use npm link
3. Inside storefront-renderer-2 run npm link @bigcommerce/stencil-paper
4. Run storefront-renderer-2 locally and turn on STRF-11672.Enable_nonce_csp_header
5. Add to script manager

<script>
    {{nonce}}
</script>

7. See that nonce is shown without outer quotes, and is also displayed in attributes section of the script tag

STRF-11672.Enable_nonce_csp_header on

STRF-11672.Enable_nonce_csp_header off

8. Ongoing work with Merc, some errors will be expected with STRF-11672.Enable_nonce_csp_header on

Given all of @huntario's testing plus me checking this version bump out locally with stencil-cli. I think this PR looks good from a QA perspective.
