broken link to Library Hat blog post in 01-regular-expressions.md

A link to a Library Hat blog post in the 01-regular-expressions.md page is broken, leading to a "Site not found" error.

It's on line 264 of the code:

lc-data-intro/episodes/01-regular-expressions.md

Line 264 in 06fa19e

This logic is useful when you have lots of files in a directory, when those files have logical file names, and when you want to isolate a selection of files. It can be used for looking at cells in spreadsheets for certain values, or for extracting some data from a column of a spreadsheet to make new columns. There are many other contexts in which regex is useful when using a computer to search through a document, spreadsheet, or file structure. Some real-world use cases for regex are included on a [Library Hat blog post](https://www.bohyunkim.net/blog/archives/2595#.YTc3rzeSkUo) .

And can also be seen a couple of lines above this link: https://librarycarpentry.org/lc-data-intro/01-regular-expressions.html#exercise on the lesson page.

It should either be removed or possibly another resource that includes real-world use cases for regex should replace it.

@bennkael Thanks for catching that! @kevintfrench was able to make a temporary fix in #211. I'd like to leave this issue open for anyone to seek out and suggest alternatives, especially if they are more recent and/or have more accessibility features.

I'm not sure if this is the best place to flag it, but it seems that the updated link from #211 (https://acrl.ala.org/techconnect/post/fear-no-longer-regular-expressions/) is also broken:
Fatal error: Access level to Gutenberg_REST_Global_Styles_Controller_6_2::validate_custom_css() must be protected (as in class WP_REST_Global_Styles_Controller) or weaker in /home/customer/www/acrl.ala.org/public_html/techconnect/wp-content/plugins/gutenberg/lib/compat/wordpress-6.2/class-gutenberg-rest-global-styles-controller-6-2.php on line 217

Alternatively, the original post (archived, but https) is available at: https://www.bohyunkim.net/blog/archives/2595

An alternative to another static blog post could be the library of community regular expressions at https://regex101.com/library as it is perhaps less at risk of link decay, and the instructors/learners could browse to showcase examples relevant to their own work/situation? It could make sense as the lesson makes heavy use of regex101.com later on for the exercises.
