…amp portion (#327)

* final tweaks for BSON 5 release

* RUBY-3435 constrain timestamp to 4-bytes

Copied additional information from the Ruby driver's README and adapted it to the `bson` gem's README

* SSDLC shenanigans...

* publish job depends on the build job

* need Ruby configured to build the native code

* fix regex anchoring (alerted via codeql)

* ignore vendor folder

* apparently we have to specify environment for each job

* see if it picks up jruby this way?

* download all artifacts to the current directory

don't create separate directories for each downloaded artifact.

* authorized-pub task doesn't like globs with spaces in them

* use boolean type for dry-run flag

* don't need to specify "false" explicitly anymore

* simplify the build phase (don't need secure checkout)

Note that only tutorials/bson.txt was actually used
in the submodule configuration, so that was the only file that was moved over.

* RUBY-3481 version bump

* talk about how to verify the gem's integrity

* try to get codeql to ignore the vendor folder

could it be that we need to set up ruby first, so that the
"ignore-paths" directive will see and ignore the additional files there
at that point?

* see if comparison w/ boolean is what we need here

* remove the step used to test the comparison
