implement ui build pipeline and complete workflows (#215)

Builds would live at:
pr builds - neuralmagic.github.io/guidellm/ui/pr/12
dev - neuralmagic.github.io/guidellm/ui/dev
staging/release-candidate -
neuralmagic.github.io/guidellm/ui/release/v1.0.0 or
.../ui/release/latest
production/release - neuralmagic.github.io/guidellm/ui/v1.0.0 or
.../ui/latest

PR builds will include mocked data, view example in comments below. All
other builds currently will be blank slates, waiting to be pulled down
and used to generate an html report.
