Review visualizations for dark/light mode compatibility

[svrnm]

While we have dark mode for a while now, some of the visualizations on our website have a white background and/or colors that are made for light mode, e.g.

• https://opentelemetry.io/img/otel-diagram.svg on https://opentelemetry.io/docs/
• https://opentelemetry.io/img/waterfall-trace.svg on https://opentelemetry.io/docs/concepts/observability-primer/
• https://opentelemetry.io/docs/collector/img/otel-collector.svg on https://opentelemetry.io/docs/collector/
• ...

It would be great if at a minimum the background for those images could be set to be transparent, so that they either are black or white, and then to check if some colors need to be adjusted to still work with light&dark mode at the same time. The overall color schema & theme should remain untouched.

Hi @svrnm, can I work on this issue? I just implemented dark mode to another open-source project.

@SuvineetSingh @Tharanishwaran we are currently running the participation phase for outreachy, and we need to reserve some good first issues for the participants. If you participate in outreachy please take a look in #5290, otherwise I can currently not assign this issue to you. When the participation phase ends, and this issue is still available, I am happy to assign it.
