Add rule that components shouldn't put silkscreen outside the board edges
Many connectors are allowed to overhang - if they include a full silkscreen outline, this is a DRC error in Kicad 7.
Instead, they should pull the silkscreen back from possible board edges.
0.5mm chosen as a clearance because this should keep clear even of v-scored edge processes.
I'm not particularly attached to 0.5mm as a number, I imagine most fabs not using v-scores will get quite a bit closer, but seems like that's probably close enough for general purposes?
