broken url

[oldoldman]

Hi guys,

1. url in at this line is broken :

   microzig/port/microchip/samd51/build.zig.zon

   Line 8 in 48582bf

   .url = "https://atpack.microzig.tech/Atmel.SAMD51_DFP.1.2.139.atpack",

2. found a similar link https://packs.download.microchip.com/Microchip.SAMD51_DFP.3.8.246.atpack and replaced with it the above url.
3. But it is not recgonized by Zig fetch

unrecognized 'Content-Type' header: 'application/vnd.atmel.atpack'

4. as a work arround, I can download the package and unpack it manually into Zig cache.
