Fixes https://github.com/status-im/status-desktop/issues/16688
Since we use the local image server to show the community image, the URL never changes when we update the image, since it's served using a query string containing the community ID. eg: `https://Localhost:46739/communityDescriptionImages?communityID=0x03c5ece7da362d31199fb02d632f85fdf853af57d89c3204b4d1e90c6ec13bb23c&name=thumbnail`
Because of that, the clients cannot know if the image was updated, so they had to force update the image every time, which was inefficient.
We discovered this issue when I refactored the community client code in Desktop so that we only update the changed properties of a community instead of reseting the whole thing.
The solution I came up with in the PR is to add a `version` to the URL when we detect that the image changed. This let,s the clients detect when the image was updated without having to do any extra logic.
