feat: follow common conventions on folder naming in `$XDG_CONFIG_HOME`

🆒 Your use case

While #526 added support for XDG_CONFIG_HOME, it stores files in $XDG_CONFIG_HOME/.nuxt/devtools instead of the convention of $XDG_CONFIG_HOME/<application>, i.e., without the leading .. The leading dot in UNIX conventions is to denote a hidden file, and with the default location of $XDG_CONFIG_HOME being ~/.config, the parent folder is already hidden and there really isn't a need to further hide the folder inside $XDG_CONFIG_HOME.

While the XDG Base Directory specification is unfortunately silent on the naming convention and folder structure inside $XDG_CONFIG_HOME, common convention is to simply name the subdir directly after the application, without the leading dot.

ℹ️ Additional info

If this is an acceptable feature, I would be willing to contribute a PR.

Locate the code that builds the $XDG_CONFIG_HOME path for devtools and inspect how the current .nuxt/devtools location is selected. Update the configuration location to $XDG_CONFIG_HOME/nuxt/devtools, then verify that devtools files use the requested path without breaking the existing default behavior.
