[pbs-devel] [PATCH backup 1/4] datastore: docs: turn uri into hyperlink

[Maximiliano Sandoval]

Fixes the cargo doc lint:

```
warning: this URL is not a hyperlink
   --> pbs-datastore/src/data_blob.rs:555:5
    |
555 | /// https://github.com/facebook/zstd/blob/dev/lib/common/error_private.h
    |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    |
    = note: bare URLs are not automatically turned into clickable links
    = note: `#[warn(rustdoc::bare_urls)]` on by default
help: use an automatic link instead
    |
555 | /// <https://github.com/facebook/zstd/blob/dev/lib/common/error_private.h>
    |     +                                                                    +
```
