Global bookmark disapears after closing vsc.

[wuqiong4945]

Describe the bug Global bookmarks disappear after closing vsc. In native VIM, it will be kept and permanent.

And a suggestion, it is better to give global bookmarks another color (for example, green), to distinguish them with local ones. Or it can be set separately.

To Reproduce

1. open a file
2. press 'm' + 'A', get a global bookmark 'A'
3. close vsc, and reopen
4. bookmark 'A' is not kept. no bookmark at all.

Expected behavior Global bookmarks are kept like native VIM.
