Handle external blogs that refer to old tools

Details about Problem

It is apparent that people are stuggling to get started when using old blogs.
Most are likely due to use of an old tool (https://www.nuget.org/packages/nanoFirmwareFlasher/) and not looking at the fact it is deprecated.
We should redirect to the new tool (if possible) since it seems to use the same "short name" as the current tool, which causes extra installation problems..

The current workaroud would be:

dotnet tool uninstall --global nanoFirmwareFlasher
dotnet tool install --global nanoff

nanoFramework area:
nanoff tool.

VS extension version:
N/A

Target:
All

Firmware image version:
All

I've reached out to Wouter Huysentruit with a dm on Twitter about a month ago, no answer and no editting of the blog post.

All versions of the old nanoFirmwareFlasher nuget packages are labeled as deprecated.

I have added a comment to the blog (which might help)...

Just published a "new" version of the old tool. That's non-functional and outputs a message, hopefully, clear enough about the deprecation and steps to follow. Don't think there is much we can do about this...
