Add wasm support

[Stygmates]

Chrono's wasm support wasn't enabled, probably because the docs were outdated and it is currently not listed in the crate's default features but is present in the README .

chronotope/chrono#1260 updates the docs on their side. I can also make a PR for oauth2-rs if you want.

Interesting, what was the impact of not having this feature enabled? I would have assumed the WASM CI build step would have failed

I ran into panicked at 'time not implemented on this platform', library/std/src/sys/wasm/../unsupported/time.rs:31:9 that I think was raised when verifying the claims, specifically at this line:

openidconnect-rs/src/verification.rs

Line 552 in 414eb35

time_fn: Arc::new(Utc::now),

.
I noticed that the implementation of now() used wasn't the correct one (this one which uses the std implementation of now which doesn't support wasm was used instead of this one) because of the feature flag

Oh ok, thanks! It looks this will require an update to the MSRV Cargo.lock file to get the 1.65 build to pass:

cp Cargo-1.65.lock Cargo.lock
cargo check
cp Cargo.lock Cargo-1.65.lock

Once that passes, I'll happily merge.

I can also make a PR for oauth2-rs if you want.

That would be greatly appreciated 🙏

This should pass now, I'll make the PR for oauth2-rs tomorrow, it's 1 AM where I live 😪

This is now released in 3.3.1

Thank you for the fast response and fast release of a new version!
