Update GitHub language breakdown

[DecimalTurn]

Currently, the language breakdown of this repo indicates 100% Visual Basic .Net. That's because the last change made to the repo was done before VBA was added to GitHub in December 2019 (via Github-Linguist v7.7).

Normally, any changes (even a space added to the README) would be enough to trigger a new analysis of the languages in the repo.
It would be nice to push a fictitious change to this project so that it can appear correctly labelled as a VBA project when people search on GitHub.

I can always create a PR for this, but I don't think this is worth adding me as a contributor 😅.

I just realized that because the file extension used for VBA code in this repo is .vb. Because this extension is associated to VB.NET on GitHub, my previous suggestion won't be enough to fix the language breakdown.

You'd also need to add a .gitattributes file to the repo with the following line:

*.vb    linguist-language=vba
