Unable to access favorite channel from dashboard with index >9

[elcoco]

First of all thank you for this amazing project!

Describe the bug:
Since the dashboard screen only accepts a single number it is not possible to access any favorite channels higher than the 10th channel.
Could possibly be solved by using [a-z][A-Z] instead of [0-9].

To Reproduce:
Configure more than 10 channels in the config file:

[frontend]
favorite_channels = ["channel0", "channel1", ..., "channel10"]

Expected behavior:
Have a way to access a favorite channel with index >9 by using a keyboard stroke.

System:

• Twitch-tui version: 2.6.17 (using arch package: extra/twitch-tui 2.6.17-1)
• Operating System: Arch Linux w/ kernel 6.12.7
• Terminal: kitty 0.38.1
• Shell: zsh 5.9-5

Thanks for the issue! That ain't good, I'll get around to this as soon as I can.
