Java 11 Blocker: Fonts not present in lambda runtime

[mmajis]

Fonts are not included in the Amazon Corretto Java 11 runtime environment.

This happens:

Need to figure out how to add fonts as a lambda layer:

• fontconfig.properties file
• actual font files as referenced in the properties file

Maybe build fontconfig and copy it over to lambda as shown here: https://medium.com/creditorwatch/aws-lambda-fonts-libfontconfig-5e837281a4ce

This got fixed by moving to a custom container based lambda. Java 11 is now the runtime and fonts could be added to the container build.
