As far as I know the only node that takes the Texture type as an Input is the Attribute Sample Texture node (note the node interface has never even been updated in the documentation).

It's deprecated starting on 3.0 but for backwards-compatibility (I guess) will be kept around at least until 3.1. You can enable legacy nodes (that is to say nodes from 2.93 version which are not officially released in 3.0+) by going Edit > Preferences > Interface > Developer Extras and then Edit > Preferences > Experimental > Debugging > Geometry Nodes Legacy.

It should not be mistaken for an Image data type which goes into an Image Texture node. The input discs are purple but the Texture one is more pink than the Image type.
