Fix do signature (#13216)
Recommend holding until after #13125 is fully digested and *possibly*
until 0.96.

# Description

Fixes one of the issues described in #13125 

The `do` signature included a `SyntaxShape:Any` as one of the possible
first-positional types. This is incorrect. `do` only takes a closure as
a positional. This had the result of:

1. Moving what should have been a parser error to evaluation-time

   ## Before

   ```nu
   > do 1
   Error: nu:🐚:cant_convert

     × Can't convert to Closure.
      ╭─[entry #26:1:4]
    1 │ do 1
      ·    ┬
      ·    ╰── can't convert int to Closure
      ╰────
   ```

   ## After

   ```nu
   > do 1
   Error: nu::parser::parse_mismatch

     × Parse mismatch during operation.
      ╭─[entry #5:1:4]
    1 │ do 1
      ·    ┬
      ·    ╰── expected block, closure or record
      ╰────
   ```  

2. Masking a bad test in `std assert`

This is a bit convoluted, but `std assert` tests included testing
`assert error` to make sure it:

* Asserts on bad code
* Doesn't assert on good code

The good-code test was broken, and was essentially bad-code (really
bad-code) that wasn't getting caught due to the bad signature.

Fixing this resulted in *parse time* failures on every call to
`test_asserts` (not something that particular test was designed to
handle.

This PR also fixes the test case to properly evaluate `std assert error`
against a good code path.
