Bump version in Yew docs to 0.19.3

[allan2]

Since 0.19.0 through 0.19.2 are yanked, the docs should reflect this.

#2312

@allan2 Thank you for your concern.

I checked the docs, we don't specify patch version anywhere in the docs. As in its 0.19 not 0.19.0 everywhere.

So when you type in 0.19 in your cargo.toml, rust will automatically select the patch version.

@voidpumpkin see this

https://github.com/yewstack/yew/blob/e1b51218ec01e10de15a18c8deb019b93e34e66b/website/versions.json#L1-L4

The version number is 0.19.0. Changing it now is annoying but we should not add the patch version in the future

@hamza1311 Thanks, indeed my bad. Reopening because we should change them to only include minor versions

[ranile]

Major and minor versions. We just need to exclude the patch version

Closing this as 0.20 has superseded it
