Fix assembly and publication of documentation on https://docs.rs/

An error occurs in the last few automated documentation builds.

The lack of documentation on https://docs.rs/ causes great discomfort during the initial acquaintance with the library.

A possible solution would be to add default = ["axum", "axum-sqlx-tx/runtime-tokio-rustls"] to the [features] section for the aide crate.

I experienced it myself, but it is undeerstandable.
The crate aims to be dependency agnostic, the best we can do is add axum-sqlx-tx to the docs.rs feature section. Adding these default features could also break builds.

it doesn't seem possible to activate those dependencies on the fly depending on what libraries are used, which would be the ideal solution if it was possible rust-lang/cargo#5499

[Wicpar]

so it seems that features can be activated using for docs.rs

[package.metadata.docs.rs]
all-features = true

which is already there.

#74 fixes this definitely by removing the conflicting dependencies from the crate.

it works even without the changes :)
