depends: update 'src/immer' to arximboldi/immer@5875f773 as c0b716f2

Additional Information

• Dependency for refactor: remove C++17 workarounds #6380

#6380 will be using std::ranges as a replacement for dash#4622 and currently, it will fail to compile due to the current version of immer (last updated two years ago in #4911) not meeting constraints (source) set by std::ranges (see below).

This has been resolved by updating immer to the latest available release, v0.8.1.

Expected subtree hash without changes are a5ded361aec714bc74149909c5e1984c10ab132c4c539c63fe57362dccd95556 (see here for verification instructions).
