Do not set status-style when disabling the nord statusline

[0phoff]

This commits fixes the code to not set the status-style option when disabling the nord-tmux status-bar.

Usually, when disabling the status-bar, it means a user wants to customize it to his/her liking.
For some reason, overriding this status-style option before creating your own bar does not seem to work.
The only way I got things working was to explicitly remove that option from your code.

By setting this option in the nord-status-content.conf and nord-status-content-no-patched-font.conf files, we ensure it gets only set when a user actually uses the provided status-bars.

Hi @0phoff 👋, thanks for your contribution 👍
I'll try to review and test the changes within the next weeks.

@0phoff Thanks for your patience, it's been busy times again.
Can you please provide a MCVE that shows how the status-style option prevents users from defining their own status bar content? I tried to reproduce it by setting the @nord_tmux_show_status_content variable to 0 and defining custom content for the right bar (set -g status-right "..."), but it works fine even the custom content is defined after loading the plugin.
