The Hessian of the `LinearAlgebra.jl` dot is incorrect

The computation of the Hessian of the `LinearAlgebra.jl` dot is wrong:

```
using ForwardDiff
using LinearAlgebra
@info ForwardDiff.hessian(x -> dot(x, ones(1,1), x), [0])
```
Produced output:
```
[ Info: [0.0;;]
```

Environment:
```
julia version 1.8.5
```
