Change DM grammar source

[vvvv-vvvv]

Description

Changed the DM grammar to a better maintained source that has new keywords

Checklist:

• I am changing the source of a syntax highlighting grammar
  • Old: https://github.com/PJB3005/atomic-dreams
  • New: https://github.com/spacestation13/dm-syntax

We can't accept this change.

Whilst the grammar files are licensed under MIT, the over-all repo is licensed by GPL-3 which means we'll be shipping code that is covered by this license which we can't do.

I'm also not sure GPL3 allows sub-licensing, but that's not relevant as we don't include just the grammar files.

[vvvv-vvvv]

Is this fine? The samples for the new extensions are about as complicated as they can get, so they aren't from a real-world project

[lildude]

No. We want real world examples as documented. This is used to train the classifier. The .dme extension is also not popular enough for addition right now so will only hold back this PR.

[lildude]

LGTM. Thanks.

Note: this PR will not be merged until close to when the next release is made. See here for more details.

Moved the repo elsewhere

[lildude]

This doesn't match the URLs used elsewhere. If you used the script/add-grammar --replace command, it should have resulted in the same URL used elsewhere.

[vvvv-vvvv]

I did, and it didn't replace this

[optimumtact]

thanks lildude
