removed uninstall nemo_cv and nemo_simple_gan and relax numba version…
   
 * removed nemo_cv and nemo_simple_gan in reinstall.sh.
 * relaxed numba version limits.
 * added tensorboard requirement to avoid any incpmpatible issue.

not quite sure why we should enforce `numba==0.55`. When I run `./reinstall.sh`, I got incompatible env issue below for `tensorboard` and `numba`.

``` bash
(nemo) xueyang@LOCAL:~/workspace/NeMo:(main)$ ./reinstall.sh

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
tensorboard 2.10.0 requires protobuf<3.20,>=3.9.2, but you have protobuf 3.20.1 which is incompatible.
numba 0.55.0 requires numpy<1.22,>=1.18, but you have numpy 1.23.3 which is incompatible.
