fix(ui): Resolves filename truncation if file contains more than one dot in Namespace Files Editor

[shivam221098]

Closes #5956

Changes

• A logical error was in ui/src/components/inputs/EditorSidebar.vue while parsing filename & extension from the file path.
• Logic to parse filename & extension from file path is changed in stored in a separate function, that's then accessed wherever we have to extract the file details.
• For removing the redundancy, a similar sort of local function separateString is replaced by the new function that contains the logic for parsing filename & extension.
• For getting extension part of the file, .split(".")[1] is replaced with .split(".").pop() at various places.

QA

• Uploaded a file with multiple dots test.0.0.0.0.0.0.0.txt, when the file is uploaded, it was visible with same name and when the page is reloaded, it was still with the same name.

• Created files with multiple dots within the folder and and outside the folder, file names are visible without any changes
  

• Ran simple flow to verify file read operations
  

• Flow

        print(file.read())
      
      with open("test/test_inner/test.ef.txt") as file:
        print(file.read())
      
      with open("out.0.0.1.side.txt") as file:
