✨ Add Anthropic block (#1336)

Hello @baptisteArno,

As we discussed in issue #1315 we created a basic implementation of
Anthropic’s Claude AI block.
This block is based on the OpenAI block and shares a similar structure.

The most notable changes in this PR are:
- Added the Claude AI block.
- Added relevant documentation for the new block.
- Formatted some other source files in order to pass git pre-hook
checks.

Some notes to be made:
- Currently there is no way to dynamically fetch the model’s versions
since there is no endpoint provided by the SDK.
  - All pre version-3 Claude models are hard-coded constant variables.
- We have opened an issue for that on the SDK repository
[here](https://github.com/anthropics/anthropic-sdk-typescript/issues/313).
- We can implement in a new PR Claude’s new [Vision
system](https://docs.anthropic.com/claude/docs/vision) which allows for
image analysis and understanding.
  - This can be done in a later phase, given that you agree of course.

+## Create Message
+
+With the Anthropic block, you can create chat messages based on your user queries and display the answer back to your typebot using Claude AI.

+    alt="Anthropic block"
+  />
+</Frame>
+
+Similarly to the OpenAI block, this integration comes with a convenient message type called **Dialogue**. It allows you to easily pass a sequence of saved assistant / user messages history to Claude AI:
+
+<Frame>
+  <img
+    src="/images/blocks/integrations/anthropic/append-to-history.png"
+    alt="Claude AI messages sequence"
+  />
+</Frame>
+
+Then you can give the Claude AI block access to this sequence of messages:
+
+<Frame>
+  <img
+    src="/images/blocks/integrations/anthropic/dialogue-usage.png"
+    alt="Claude AI messages sequence"
+  />
+</Frame>
+
+Finally, save the response of the assistant to a variable in order to append it in the chat history and also display it on your typebot.
