feat(Sender): support custom paste text filter via pasteFilter prop

Hi!

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @ant-design/x@2.5.0 for the project I'm working on.

Problem

When using Sender with slotConfig mode, pasting multi-line text into the textarea causes all line breaks to be stripped by the internal getCleanedText() function. This makes it
impossible to preserve the original formatting of pasted content.

In our use case, users frequently paste code snippets or structured text that rely on line breaks for readability. The automatic cleaning removes this formatting, degrading the user
experience.

Proposed Solution

Add a pasteFilter prop to SenderProps that allows users to provide a custom paste text filtering function. When provided, it replaces the default getCleanedText() behavior, giving users
full control over how pasted text is processed.

Here is the diff that solved my problem:

This issue body was partially generated by patch-package.

Start by comparing the mentioned Sender.js, components/SlotTextArea.js, and interface.d.ts files with their source counterparts, focusing on how paste handling and SenderProps are wired. Verify the custom filter preserves or transforms pasted text as requested, while the existing default behavior remains unchanged.
