Option to Prevent Trailing Slash on baseUrl in Cypress Config

[josefnorlin-svt]

What would you like?

A property in the cypress.config.ts file to lock the baseUrl so that Cypress does not add an extra / at the end.

Why is this needed?

Relating to #5269 we too face the same problem. In our case, we're using HashRouter in React and need to set the baseUrl like this:
https://domain.com/index.html#specific_route

As @dialex mentioned, Cypress automatically appends a trailing slash (/) to the baseUrl, which results in:
https://domain.com/index.html/**/**#specific_route
instead of the desired:
https://domain.com/index.html#specific_route

This causes all of our tests to fail.

Since setting a global baseUrl is considered best practice in Cypress, it's frustrating to have to work around this by using an environment variable instead.
For us, @dialex, and others facing the same issue, adding an option in cypress.config.ts to prevent Cypress from automatically adding a trailing slash to the baseUrl would be a great solution.
For example, a property like lockBaseUrl: true could be introduced to preserve the exact baseUrl as defined.

Cypress treats index.html like a folder, which can result in an automatic trailing slash being added to the URL. To prevent this, you can append a character—like a hash (#)—to the end of your baseUrl.
For example, instead of setting the base URL to https://domain.com/index.html, use https://domain.com/index.html#. This prevents Cypress from interpreting it as a directory, avoiding the unwanted trailing slash.

A suggestion from cy.david from cypress community is : try overwriting the cy.visit command and stripping any trailing / in the urls
