fix(charts): quote annotation values

[mboersma]

I get errors trying to set service_annotations or deployment_annotations in testing #323. Templating the router service seems to be the initial problem, because the range loop doesn't quote the values as required.

Closes #325.

I think there's a quote function in sprig for this that might be safer to use here. It will escape any double quote that exists within the string to make it YAML safe.

Good point--I'll try | quote.

I'll see if I can get service annotations working with this fix.

This worked for me. LGTM!
