onetbb: require conan 2.0.8 because of 'cmake_config_version_compat'

[ilya-lavrenov]

Specify library name and version: onetbb/2021.9.0

See conan-io/conan#13809
Without increasing Conan minimal version, this option has no effect

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

It seems excessive. cmake_config_version_compat is no-op with with conan < 2.0.8, and it doesn't matter for most people.

Without increasing Conan minimal version, this option has no effect

I think there may be a misunderstanding - the option has an effect for users on Conan version 2.0.8 or higher, irrespective of the required_conan_version value in the recipe. By increasing it to required_conan_version this would force everyone using Conan 2.0 to be on at least that version, when it's not technically required. find_package(TBB X.Y) specifying a version will only work for users on Conan >= 2.0.8 and a recent recipe revision, but find_package(TBB) should work for everyone.

Closing, as @jcar87 and @SpaceIm pointed out, requiring >=2.0.8 is excessive in this case :)
