rhysd/hgrep v0.3.0 on GitHub

Update syntect dependency to v5.0.0. Thanks to lazy loading, this change makes loading assets at startup about 70% faster. The small benchmark showed hgrep command was 1.7x faster when searching a small file with -p syntect compared to v0.2.8.
Update bat dependency from 0.20 to 0.22. This introduces several improvements and fixes which were recently added to bat when using -p bat.
Add --generate-man-page flag to generate a manual page file. Save the output to your man directory to show the help with man command. If you install hgrep with Homebrew, it will be automatically generated.
```
hgrep --generate-man-page > /usr/local/share/man/man1/hgrep.1
man hgrep
```
Add several syntax highlighting for configuration files (Git configs, Fish history, SSH config, Nginx config, ...).
Wrap the --help output looking at the terminal width. The output is more compact than v0.2.8.
Improve error handling when failing to enable ANSI color sequence support on Windows.
