perf: enable equation numbering in MathJax (#1520)
If you place your equations inside $$\begin{equation}...\end{equation}$$
you will get MathJax equation numbering. As described here:
https://docs.mathjax.org/en/latest/input/tex/eqnumbers.html

BREAKING CHANGES: if you used \begin{equation} inside $$ you will
get equation numbering which was not previously present.

This post is to show Markdown syntax rendering on [**Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork), you can also use it as an example of writing. Now, let's start looking at text and typography.

Phasellus semper dui non purus ultrices sodales. Aliquam ante lorem, ornare a feugiat ac, finibus nec mauris. Vivamus ut tristique nisi. Sed vel leo vulputate, efficitur risus non, posuere mi. Nullam tincidunt bibendum rutrum. Proin commodo ornare sapien. Vivamus interdum diam sed sapien blandit, sit amet aliquam risus mattis. Nullam arcu turpis, mollis quis laoreet at, placerat id nibh. Suspendisse venenatis eros eros.

Click the hook will locate the footnote[^footnote], and here is another footnote[^fn-nth-2].
## Inline code
This is an example of `Inline Code`.
## Filepath
Here is the `/path/to/the/file.extend`{: .filepath}.
## Code blocks
### Common
```
This is a common code snippet, without syntax highlight and line number.
```
### Specific Language
```bash
if [ $? -ne 0 ]; then
echo "The command was not successful.";
#do the needful / exit
fi;
```
### Specific filename
```sass
@import
"colors/light-typography",
"colors/dark-typography";
```
{: file='_sass/jekyll-theme-chirpy.scss'}
## Mathematics
The mathematics powered by [**MathJax**](https://www.mathjax.org/):
$$
\begin{equation}
\sum_{n=1}^\infty 1/n^2 = \frac{\pi^2}{6}
\label{eq:series}
\end{equation}
$$
We can reference the equation as \eqref{eq:series}.
When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are
$$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$
