feat: allow users to enter partial/complete channel to fetch conversation

[VibhorGits]

Updated the tasks.json file.
Allowing slack to read multiple channel-names by changing type from (string-->array).
For example:
typing 'dev' retrieves conversations from all channels containing 'dev'."

Because

• Currently users need to type the entire channel name to fetch conversation.
  By implementing this functionality users can fetch by partial/complete typing.

Hey @chuang8511
Checkout my changes and let me know if some further work is required.

Hi @VibhorGits ,
you missed this part. Could you implement it?

[VibhorGits]

Hey @chuang8511 do I need to implement the execution logic from scratch or make the changes only for reading messages in the file say main.go file or tasks_function.go (as per my understanding).

[chuang8511]

You need to modify this function.

Now, the readMessage only reads a channel. Now, we want it to be able to read channels.

@chuang8511 What about changing the task_function.go file
I think we need to change there as well?

Yes, that is mainly what I mean!

Hey @chuang8511 I have made the necessary changes. Should I open another pr?

[VibhorGits]

Hey @chuang8511 I made changes in another branch and opened a separate pr.
Here are the changes in the pr: #788

[chuang8511]

Please put them in the same PR and do the testing including:

• unit test
• end-to-end test

[VibhorGits]

@chuang8511 I dont know how to put them into same pr

[VibhorGits]

Hey @chuang8511 I tried running the backend on my mac but couldn't run due to hardware specs.
Here's the thread: https://discord.com/channels/928991293856681984/1298346473561526273
I dont think I will be able to perform the testing locally on my pc.
Regarding the pr process may I ask you to review it for me?
