add close tag

[KINGSABRI]

Hi, Thank you for making admonition available.

Can you add an ability to close the tag with a tag instead/in addition to using the pip character |? The idea is to be like this

[[info | Info]]
HERE INFORMATION
[[/info]]

instead/in addition to

[[info | Info]]
| HERE INFORMATION
|

Thank you

The reason for that is when we use the same makdown document on another editor than inkdrop, it messes the format.
