"a few exceptions" link is broken

[rmcloughlin]

In this section: https://webassembly.org/docs/portability/#assumptions-for-efficient-execution there is a link titled "a few exceptions" which goes to:

https://webassembly.github.io/spec/core/exec/index.html#floating-point-operators

but it should go to

https://webassembly.github.io/spec/core/exec/numerics.html#floating-point-operations

Thanks, this is acutally a pass-through to the design repo, so I moved the issue.
