update docs links

[tzemanovic]

This PR updates links to the Book and Rustdoc to https://proptest-rs.github.io/proptest and https://docs.rs/proptest, respectively.

Additionally, there used to be a separate build for no-std deployed at https://altsysrq.github.io/rustdoc/proptest-nostd/latest/proptest/. Instead of 2 docs builds, the commit 274f6ad0e6da816dbf7cee9d5782df0770ebeb4e exposes features to the regular docs.rs build using the guide from https://users.rust-lang.org/t/how-to-document-optional-features-in-api-docs/64577/3

edit: docs.rs issue has been fixed

Do not merge yet - There seems to be an issue with the latest release on https://docs.rs/proptest/latest/proptest/ - for some reason the macros are not showing so the links from the book to the macros rustdoc are broken. They are showing in the prev version and when I build docs locally so not sure what's up with that

looks great overall, but not sure what you mean by "for some reason the macros are not showing...", do you have a link?

thx! See https://docs.rs/proptest/1.1.0/proptest/index.html vs https://docs.rs/proptest/1.0.0/proptest/index.html - the former is missing the macros section and none of the macros appear elsewhere in the docs either (https://docs.rs/proptest/1.1.0/proptest/macro.prop_assert.html vs https://docs.rs/proptest/1.0.0/proptest/macro.prop_assert.html)

i see, wiled guess but is the addition of cfg_attr in various places causing that disappearance? if not then i agree that in issue should be filed with docs.rs

It is from the last release so I don't think it could be, but I'm unable to reproduce it locally on that tag either. Thanks anyway! I've opened an issue here https://github.com/rust-lang/docs.rs/issues/2105
