The version defined in fluentd CMakeLists not match the version in CHANGELOG

[zurex]

Steps to reproduce

• The version defined in fluentd CMakeLists is 1.1.2

  • opentelemetry-cpp-contrib/exporters/fluentd/CMakeLists.txt

    Line 186 in 6a11053

    set(OPENTELEMETRY_CPP_FLUENTD_VERSION "1.1.2")

• The version in CHANGELOG is [2.0.0] 2023-06-30

  • opentelemetry-cpp-contrib/exporters/fluentd/CHANGELOG.md

    Line 16 in 6a11053

    ## [2.0.0] 2023-06-30

What is the expected behavior?
set(OPENTELEMETRY_CPP_FLUENTD_VERSION "2.0.0")

What is the actual behavior?
set(OPENTELEMETRY_CPP_FLUENTD_VERSION "1.1.2")

Additional context
What's more, we should support versioned libs since opentelemetry-cpp has such behavior.

Could i raise a PR to address this issue?
