UI - "Rename" option for thread is not working

[sangee2004]

gptscript version v0.0.0-dev+160a7334

Steps to reproduce the problem:

1. Launch ui (with or without GATEWAY_URL).
2. Create a thread by running a script and have some conversation in the thread,
3. Try to change the thread name.

User is presented with this popup page has "localhost: says" as page title

Expected Behavior:
Change the title of the page to not include "localhost:<port>" and have a more meaningful title.

@cjellick This is an artifact of the fact that Electron doesn't support the "prompt" browser function. We'll want to just add a modal here for it.

When testing with Version - 0.10.0-rc3 (release binaries) , clicking on "Rename" does nothing.

Tested with electron build - d7b8724e17c0d5dc

Able to work with "Rename" option to rename threads.
