[GSoC] [PATCH v3 0/3] t9811: Improve test coverage and clarity

In order to expose more testing outputs, we remove the piping of `git tag` outputs in order to expose the exit codes. In addition, we remove `-q` tags on instances of `grep` to ensure clarity. We also replace `grep` with `test_grep` to provide helpful debug output in case of test failure.

--------------

changes in v3:
- patch #1 and #2 were missing my sign-off, which has now been added.
- patch #2 referenced a line number, which was not informative. A new 
  discription has been added referencing the context of the code.

changes in v2:
- patch #2 and #3 have been added to reduce confusion caused by the 
  implications of `grep` followed by `grep -q`, and increase debug 
  output.
