fix: sdk local scene dev hot-reload

[pravusjif]

WHY

Hot-reload is not working beyond the 1st reload.

WHAT

Removed unneeded CacheCleaner usage that randomly breaks hot-reload. (introduced recently at #3595)

TEST INSTRUCTIONS (hot-reload)

1. Download this test scene
2. Enter the scene root folder and run npm i and then npm run start -- --explorer-alpha
3. Close the Explorer that auto-opened. Leave the scene running in the console/terminal.
4. Download the build from this PR and connect it to the running scene using the console command according to your OS
5. Once the scene loads, leave the Explorer running and in any text editor open the index.ts file of the scene that you have running
6. Modify any Vector3 value (for example change Vector3.create(32, 0, 32) to Vector3.create(15, 0, 15)), save the file and confirm that the scene gets automatically re-loaded in the Explorer that you left running in the previous step
7. After the automatic reload finishes, repeat step 6 several more times to make sure hot-reload keeps working beyond the first one
