Continue demo builds (#1600)

This PR adds the `fail-fast: false` configuration to the v2 build demo
Action. Currently, when building multiple demos (e.g. master or dev
branch builds) a single failing demo will halt the build process. With
this configuration, the build will continue and attempt to build all
demos, even if one or more fails. All demos must still build
successfully for further steps of the pipeline to be triggered.
