docs: make `noDevtoolsWarning` description less ambigous

[scarf005]

as discussed in discord, current description was ambiguous.

EDIT:

Disables the 'HOLD UP' banner in the console. As a side effect, also prevents Discord from hiding your token, which prevents random logouts.

This can be interpreted in two ways:

• noDevtoolsWarning prevents discord from hiding your tokens.
• noDevtoolsWarning prevents random logouts.

OR:

• noDevtoolsWarning prevents discord from hiding your tokens.
• Discord hiding your token prevents random logouts.
