Readme and docs should clearly state no support for Fable

查看仓库 README 和 issue 中链接的官方文档，然后将其中关于 Fable 支持的表述与 issue #204 进行比较。更新这两处内容，明确说明 FSharp.Data.GraphQL 不支持 Fable，并加入 Snowflaqe 链接；完成标准是新加入者不会被告知 Fable 受支持。

Description

FSharp.Data.GraphQL doesn't work for Fable. There is nothing about it mentioned in the readme and the docs say the opposite, that it is supported.

After sitting with it for a couple of hours to at least make it compile I tried to run it and got a lot of exceptions. Searching through the issues I discovered that there is no support for Fable in the latest version, the issue is 2 years old.

Repro steps

Steps to reproduce the problem

1. Create a Fable project
2. Add FSharp.Data.GraphQL, configure schema, create provider, make your queries etc
3. Run the project.

Expected behaviour

Either the library works for Fable, or it clearly states that it doesn't.

Actual behavior

Fails runtime with various different exceptions. The docs says Fable is supported, the readme is silent about it.

Please, clearly indicate in the readme, and especially in the official docs that it doesn't work for Fable. It can save people a lot of time, especially those who are new (like me) to Fable. Also, please, point to the great and only solution for working with graphql and Fable right now - Snowflaqe.

Thank you!
