Proposal: Regarding adding the display of the old version of OpenTelemetry Semantic Conventions on the official website

[flc1125]

OpenTelemetry Semantic Conventions 1.28.0

I found that the surrounding ecosystems based on this specification (including, for example: languages, vendors) are relatively lagging behind. They may still need time to adapt to the new specification.

I can understand that this is a relatively long process. Just in daily use, I need to combine the language and the vendor used to select the current latest version. And this latest version should be the latest version supported by both the language and the vendor.

So, a situation that I often encounter is that I need to check the documents of the previous old versions to adjust my code.

For this reason, I think many people should have this situation. So, I urgently hope that the official can support the viewing of the online documents of the old versions.

Some materials:

• Some previous proposals: Add /schemas in YAML, /schemas/list in HTML, and a 404 page for the rest #3537

Temporary solution:

I currently select the corresponding version through the Github repository to view the relevant information, but this is obviously not as convenient as the official website.

ex: https://github.com/open-telemetry/semantic-conventions/tree/v1.26.0/docs

Thank you for raising this @flc1125!

@open-telemetry/docs-approvers @open-telemetry/spec-sponsors @open-telemetry/technical-committee please take a look

I'm progressing (very) slowly towards supporting versions:

• Support spec versions #4499

Much work needs to be done before then, so I'm not making any promises.
@svrnm et al. - maybe we can close this issue as a dup of 4499? I'll record my progress in 4499.
