Config loading but not held in memory

[walkerh]

At least on my machine, the configuration would not stay in memory unless I explicitly forced tcConfigColors and orderedConfig to be global by adding the -g option to declare.

My system:

• zsh 5.9 (x86_64-apple-darwin22.0)
• Oh My Zsh ohmyzsh/ohmyzsh@803e1a7
• macOS 13.6.3 (22G436)

Here is my patch:

diff --git a/iterm-tab-color.plugin.zsh b/iterm-tab-color.plugin.zsh
index 625ab19..f6c3021 100644

+declare -ga orderedConfig
 while IFS="=" read -r configKey hexValue || [ -n "$hexValue" ]; do
   if ! ( [[ $configKey == \#* ]]); then
     orderedConfig+=( $configKey )

Thoughts? Do you want a PR with this?
