template projects fail to build in version 0.6.14

[c0per]

Describe the bug
A newly created leptos project (using cargo leptos new --git leptos-rs/start-axum) fails to compile.

To Reproduce
Steps to reproduce the behavior:

1. Run cargo leptos new --git leptos-rs/start-axum and choose not to use nightly features. (I haven't tested if the nightly fails too)
2. Go to the newly created project and run cargo leptos watch
3. See the error

Expected behavior
It runs correctly.

What seems to be the problem
The newly merged PR #2828 seems to be the problem. It updates web-sys from 0.3.69 to 0.3.70. To silence some deprecation warnings, it use some newly added api of web-sys 0.3.70 and correctly update web-sys dependency.

But the 0.6 branch has a problem, PR #2830 intend to do the same thing, but it forget to update web-sys dependency of server-fn.
So the 0.6.14 version resolves to use web-sys 0.3.69, which fails to compile.

I think the version resolution here actually has to do with wasm-bindgen. The following steps resolve the issue:

1. Install latest cargo-leptos so we can use wasm-bindgen 0.2.93
2. Update Cargo.toml in the project to wasm-bindgen = "=0.2.93" (from 0.2.93)

The project builds.

I've updated the templates so will close this, it should work.
