Improve performance of demo workspace - Rename getImageAbsoluteURIOrBase64 function (#6282)

### Description

1. This PR is a continuation of a previous PR:
https://github.com/twentyhq/twenty/pull/6201#pullrequestreview-2175601222

2. One test case was removed here:
`packages/twenty-front/src/utils/image/__tests__/getImageAbsoluteURI.test.ts`
because since we are not handling base64 images anymore, the result is
the same of the last test case. Would you rather we update the test
instead?
