docs: Add x eget installation method

[lunrenyi]

Add x eget as an installation method for dnsglobe.

x eget allows users to install dnsglobe directly from its GitHub release:

x eget use 514-labs/dnsglobe

x-cmd is a modern Shell toolkit that gives AI agents and developers powerful, portable, and composable command-line capabilities.

By the way, I'd also like to introduce x-cmd/install.

It is an open-source community dedicated to collecting and maintaining more installation methods for more software.

If your project has an installation method that you'd like to make available to more users, you're welcome to contribute it to the community.

Once added, users can browse and search for available installation methods at x-cmd.com/install, or discover and install these tools directly through the x install command.

Project authors are also very welcome to contribute installation methods for their own projects and share them with the community!
