v2.1 - Minor improvement

In this version, action will automatically escape " and \ characters.
This is just a minor improvement for those who don't want to deal with escaping.

v2 - File upload and more

And this should mark the completion of this action.
The most notable addition to this version is file upload!
I've also added support for components (but you need an application-owned webhook to use them).

v1.4 - A lot better

After a lot of working, testing, and once again testing, I've finally (hopefully) tested this action throughout and fixed some major bugs.

• You can finally send messages with only content set
• Fixed allowed mentions
• Embeds are now able to include multiline text without the need to write \n
• Debugged the issue where you can't run this action multiple times in one job. Turns out, this is a bug in Github Actions, and I can do nothing about it. (added warning in README)

v1.3 - Multiline the way

Finally got the multiline working

Initial public release

Finished writing this action, made a tag, and then needed to fix something, so v1.1 is the first public release.
Anyways, enjoy!
