Publish recent documentation under a fixed version number

[Seungpang]

Description

Currently, Micrometer publishes the latest documentation at https://docs.micrometer.io/tracing/reference, but does not provide a version-specific link for each release. This issue makes it challenging to reference a specific version of the documentation.

For example, linking to version 1.2 can be done via Micrometer Tracing v1.2, but attempting to link to version 1.3 via Micrometer Tracing v1.3 results in a 404 error.

Rationale

Having version-specific documentation links is crucial for referencing and ensuring users access the correct version of the documentation.

Additional Context

This issue is similar to the one raised for Micrometer's main documentation in spring-projects/spring-boot#40916.

• https://docs.micrometer.io/tracing/reference/1.3/configuring.html#_exemplars
• https://docs.micrometer.io/tracing/reference/1.3/
