Describe the bug

When I add a title to a callout block header, the rendering doesn't keep the space between the text properly.

Expected behavior

I expect the Title to have spaces between the callout block and the title

While this plugin supports callouts it does not support callouts with custom titles, this is a feature request not a bug.

Github's parser fails to preview them as well, if you try out:

Here's the result:

Normal callouts work though:

Requested feature comes from obsidian: https://help.obsidian.md/Editing+and+formatting/Callouts#Change+the+title

[MeanderingProgrammer]

Ive added support for custom callout titles as documented by obsidian in this commit: https://github.com/MeanderingProgrammer/markdown.nvim/commit/a1bcbf4858d1834f922029b5fc6ae55a7417bd51

Please update and LMK if it works!
