swift-tools-version:5.8 have deprecated the use of .package(name:xxx, url:xxx, from:xxx) to .package(url:xxx, from:xxx).
This causes our internal SPM using 5.8 to break

Update LD SPM to support 5.8

In case 5.8 is a concern (since it becomes the minimum), I believe keeping 5.2 would still work

Hi @pierre-wehbe , thanks for opening this PR. One of our team will take a look to verify this has no adverse effects on our packages. Thank you!

HI @pierre-wehbe . We will be releasing support for XCode15 in the near future. During this work, we looked at the swift-tools-version you have proposed. Unfortunately that bump would be too drastic for our customer base at the moment. We are going to be bumping it from 5.2 to 5.3 however. Are you able to have your build process ignore the deprecation?
