Tools: Modified version mismatch msg to be warning instead of error

[cmonr]

Description

It was mientioned, but slipped in the original PR that the version mismatch message be a warning instead of an error. The current mesasge is prefixed with [Error] which appears to be confusing users since the build continues (sometimes just fine).

This PR changes [Error] to [Warning]

@cmonr Can we proceed this one, there was another recent report regarding this error (it is not error but just a warning, build continues).

[0xc0170]

[cmonr]
