Documentation of pathlib.Path methods is disorganised

Documentation

The docs for pathlib.Path methods is disorganised. It was originally alphabetical, but over the last few years we've begun moving similar methods together. We ought to split it up into sections, to make it easier to navigate and absorb, e.g.:

• Parsing and generating URIs
• Querying file type and status
• Reading and writing files
• Iterating over directories
• Making paths absolute
• Expanding home directories
• Resolving symlinks
• Permissions
• Ownership
• Other methods

If this granularity is too fine, we could stick more stuff in "Other methods".
