[v4.1] CXX-3663 bump downloaded C driver to 2.1.2 (#1474)

* bump auto-downloaded version to 2.1.2
  * Keep required version the same to avoid a minor version dependency bump in a patch release.
* regenerate SBOM-lite
* check for `bson.h`
  * `bson-config.h` was renamed in CDRIVER-4153. Use `bson.h` since it is included directly.
* update augmented SBOM from Evergreen task
* fix referenced tag in purls.txt
  * `v2.1.2` to `2.1.2`
* get augmented SBOM from Evg
