chore(vrl): Revert use new value crate for type checking in VRL

[jszwedko]

Reverts #11222

This introduced a backwards incompatible change to VRL that broke the http_pipelines_blackhole soak tests. See https://github.com/vectordotdev/vector/runs/5126198293?check_suite_focus=true

The failure is:

error[E103]: unhandled fallible assignment
   ┌─ :19:13
   │
19 │     .tags = push(.tags, tag)
   │     ------- ^^^^^^^^^^^^^^^^
   │     │       │
   │     │       this expression is fallible
   │     │       update the expression to be infallible
   │     or change this to an infallible assignment:
   │     .tags, err = push(.tags, tag)
   │
   = see documentation about error handling at https://errors.vrl.dev/#handling
   = learn more about error code 103 at https://errors.vrl.dev/103
   = see language documentation at https://vrl.dev/

It's unclear from the PR if this was intended or not. If it was intended, we should update add an upgrade hightlight given it is a break in compatibility and update the soak test.
