[Bug]: Internal section links in docs (markdown) do not work

### Describe the issue

The internal section links (by heading ID) are not working (at least not in GitHub's markdown renderer).

Example:
https://github.com/google/googletest/blob/5ab508a01f9eb089207ee87fd547d290da39d015/docs/reference/assertions.md?plain=1#L159-L160
contains the link for this section:
https://github.com/google/googletest/blob/5ab508a01f9eb089207ee87fd547d290da39d015/docs/reference/assertions.md?plain=1#L261
```
https://github.com/google/googletest/blob/main/docs/reference/assertions.md#floating-point
```
but GitHub does not take you to the "Floating Point" section. Instead this would be the correct link:
```
https://github.com/google/googletest/blob/main/docs/reference/assertions.md#floating-point-comparison-floating-point
```

It seems that by trying to place the shorthand heading ID `(#floating-point)` in the heading text itself, it has caused GitHub's .md renderer to not recognize `floating-point` as the correct heading ID.

There are many headings and links that have this same issue in this file, and this may affect other files too, if they follow the same heading format.

### Steps to reproduce the problem

1. Navigate to this page (linked in the binary comparison section of the Assertions reference doc).
```
https://github.com/google/googletest/blob/main/docs/reference/assertions.md#floating-point
```
or click here: https://github.com/google/googletest/blob/main/docs/reference/assertions.md#floating-point
2. Observe that the floating point section is not opened.
3. Navigate to this page (proposed link correction).
```
https://github.com/google/googletest/blob/main/docs/reference/assertions.md#floating-point-comparison-floating-point
```
or click here: https://github.com/google/googletest/blob/main/docs/reference/assertions.md#floating-point-comparison-floating-point
4. Observe that the floating point section is *now* opened.
