fix: replace deprecated bare range expressions in tests with list literals

Bare range expressions like `{ 1..10 }` used as constructor arguments are
deprecated in newer F# compilers (error FS3873). Replace with list literals
`[1..10]` in two places in TaskSeq.Concat.Tests.fs.

This fixes a build failure with .NET SDK 10.x / F# 9.x and later.
