Consider renaming repository (back) to nord-tmux due to "tmux" being the tpm plugin name

[ericvw]

Regarding the migration mentioned in nordtheme/tmux#78, the result of the installation is the plugin named tmux because the tmux plugin manager only uses the repository name as the plugin name.

Output from prefix + I below:

Already installed "tpm"                                                                        [0/0]
Installing "tmux"
  "tmux" download success

TMUX environment reloaded.

Done, press ENTER to continue.

Could the repository be renamed back to nord-tmux; or tmux-nord to keep the tool name to the left to be closer in consistency with the names of the other repositories?

As an aside, I just started porting all my tools to Nord as I have recently stumbled across this great color palette and associated themes — thank you for all of this and the great post in nordtheme/tmux#78 that outlines the future of Nord!
