[Feat]: urge upgrade of code-server based on discontinued version.

## What is your suggestion?
Currently, we have users using the old version of code-server and submitting bug reports. we should maintain a column on the release page mentioning which version of code server support is being discontinued. the discontinued versions can be decided based on vscode release version. the discontinued versions issues will be less prioritized and the user who submitted the bugs are encouraged to check the issue again in updated version of code-server
## Why do you want this feature?
The above feature should throw a popup to users using the old version of code-server. it can be made in the below methods.
1. Minor version upgrade is available (4.5.0 to 4.5.1)- popup once a week
2. Minor version upgrade not done in several weeks - (4.4.0 to 4.5.1 where there has been an upgrade from 1.68.x to 1.69.x) - every time user logins & bottom status bar in orange color
3. Not upgraded from old versions (4.1.x ) - frequent upgrade notifications & bottom status bar in Red color

## Are there any workarounds to get this functionality today?
No
## Are you interested in submitting a PR for this?
No
