fix: Total and Used Ram in Example and Add Videos for Examples

[Tahinli]

Total and used ram was showing like TB and GB level in system information example, but the actual values are GB and MB.
I added videos about examples that don't have visual showcase.

I think we definitely don't want to link to assets in your fork
you should just use github and drag and drop the videos e.g. into an issue or into the readmes to get them uploaded and get a link to them like this

Actually i just dragged and dropped into readme files.
As i understand you are trying to copy video links and add to repositories, instead of doing this why dont you just edit (if needed [ i had given permission to edit this pr already]) then merge into proper repository. So this links will be "our" instead of "mine". Basically i will delete my repo after pr ( i just fork when i need then delete when it's done) so link will be "yours".

But if still something wrong or i miss something, i try to fix, if you show me how to do.

Thanks for this! 🙇

Could we move this work to https://github.com/iced-rs/iced-rs.github.io by creating a PR for each video file and adding it in the static/examples folder? This way, it'd be easier for us to review and iterate on the videos.

I can update the READMEs myself afterwards.

I will merge the first commit here with the work in #2223.
