overlapping memory ranges issue with some examples

[chenrui333]

👋 while regression test picotool 2.0.0, found some overlapping memory ranges errors for hello_usb, blink, and blink_simple

the error is below:

$ picotool info hello_world.uf2
ERROR: Found overlapping memory ranges 0x10000000->0x10000100 and 0x10000000->10000100

relates to https://github.com/Homebrew/homebrew-core/pull/190736

Could you confirm how you created hello_world.uf2? None of the examples mentioned create a UF2 with that name, and I cannot reproduce that error when compiling any of those examples myself.
