[Bug]: EXPECT_THAT matchers Throws and ThrowsMessage are missing from the documentation

### Describe the issue

I really like the addition of `Throws` and `ThrowsMessage`. I noticed that they appear to be missing from the [Matchers Reference page](https://google.github.io/googletest/reference/matchers.html).

### Steps to reproduce the problem

Visit the [Matchers Reference page](https://google.github.io/googletest/reference/matchers.html) and search for `Throws` and `ThrowsMessage`, with no results.

### What version of GoogleTest are you using?

latest

### What operating system and version are you using?

N/A

### What compiler and version are you using?

### What build system are you using?

N/A

### Additional context

_No response_

Open the linked Matchers Reference page and verify how existing matcher entries are organized. Document Throws and ThrowsMessage there, then confirm that both names and their relevant details appear in the published reference.
