`utils/run-test` can't infer swift build directory

[valeriyvan]

GettingStarted recommends runnings tests as:

utils/run-test --lit ../llvm-project/llvm/utils/lit/lit.py \
  ../build/Ninja-RelWithDebInfoAssert/swift-macosx-$(uname -m)/test-macosx-$(uname -m)

Being launched from swift directory it produces error:

utils/run-test --lit ../llvm-project/llvm/utils/lit/lit.py \
  ../build/Ninja-RelWithDebInfoAssert/swift-macosx-$(uname -m)/test-macosx-$(uname -m)        
run-test: Can't infer swift build directory

Probably, GettingStarted.md should give more accurate instructions.

If you have a moment, I would kindly request that you check #70605 , please.

No, addition in #70605 doesn't make issue any clearer.

This pertains to case 1:

When the command is initiated from the swift directory, it results in an error. For this reason, the command should not
include the swift keyword nor should it specify paths starting from the swift directory. It is recommended to omit the swift
keyword to avoid such issues.

Commands I used didn't have swift keyword, paths starting from swift directory wasn't specified either.

Thank you for your comments.
Upon further testing, I've found that the results differ from my initial tests, suggesting that this issue might be beyond my current scope of resolution. Therefore, I will proceed to close this PR.
