fix: URL-encode document names in document index client requests

Prior to this commit, we did not URL-encode document names when querying
the document index. This caused problems when names have special
characters, i.e., '/' or '?'. We do not need to URL-encode other parts
of the URL (e.g., namespace or collection) as these are already
constrained to URL-safe characters. In addition to this fix, this commit
includes the following changes:
- update `DocumentPath.from_slash_separated_str` to correctly delimit
  paths whose document name contains a forward slash. Ideally we'd
  remove both this and `DocumentPath.to_slash_separated_str` in the
  future.
- parametrize tests to include special characters and increase coverage
- migrate to new document index collection to avoid CI conflicts
