Introduce HashRouter

[jitu5]

Description

Resolves #2048

This pull request includes changes to improve URL handling and routing in the application. The most important changes involve, switching from BrowserRouter to HashRouter and updating the pathname generation logic.

To fix the demo site issue, We need to move to hashRouter so now new url looks like this
https://jitu5.github.io/#/?types=nodes,datasets&pid=__default__&expandAllPipelines=false&sid=1e3cc50a

Accessing the experiment tracking page directly via the URL https://jitu5.github.io/#/experiment-tracking is working as expected.

The old URL without a # will work as expected, as a check has been added for redirection.

Development notes

Improvements to URL handling:

• src/components/app/app.js: Added logic to ensure the URL hash is correctly set when the component mounts.

Routing changes:

• src/components/wrapper/wrapper.js: Switched from BrowserRouter to HashRouter to handle routing with URL hashes.

Pathname generation logic:

• src/utils/hooks/use-generate-pathname.js: Updated the useGeneratePathname hook to push the new URL only if it differs from the current URL.

QA notes

I have deployed the changes to Github pages https://jitu5.github.io to test.
