Add tags for boost versions

[iboB]

I see that new boost versions are being added to the repo, but the repo tags aren't updated.

Can you please update the tags to make it easier for shallow clones or other tag-based downloads?

This would be really cool as it would help in using this repo with CPM. CPM uses the tags for versioning.

FYI, for use with CPM, I ended up doing the following (bypassing this repo since I only need header-only parts of boost anyway and to be able to update the version of boost when I want):

CPMAddPackage(
  NAME Boost
  VERSION 1.76.0
  URL https://boostorg.jfrog.io/artifactory/main/release/1.76.0/source/boost_1_76_0.tar.gz
  DOWNLOAD_ONLY True 
)
if(Boost_ADDED)
  # Define the header-only Boost target
  add_library(Boost::boost INTERFACE IMPORTED GLOBAL)
  target_include_directories(Boost::boost SYSTEM INTERFACE ${Boost_SOURCE_DIR})

  # Disable autolink
  target_compile_definitions(Boost::boost INTERFACE BOOST_ALL_NO_LIB=1)
endif()

target_link_libraries(<your_target> Boost::boost)
