[bash/en] Fixed formatting for The Black Hole
- [x] I solemnly swear that this is all original content of which I am the original author - [x] Pull request title is prepended with `[language/lang-code]` - [x] Pull request touches only one file (or a set of logically related files with similar changes made) - [x] Content changes are aimed at *intermediate to experienced programmers* (this is a poor format for explaining fundamental programming concepts) - [x] If you've changed any part of the YAML Frontmatter, make sure it is formatted according to [CONTRIBUTING.md](https://github.com/adambard/learnxinyminutes-docs/blob/master/CONTRIBUTING.markdown) - [x] Yes, I have double-checked quotes and field names!
