Update license info

[Niki4tap]

Keeping license texts in sync with other rust repos (design repo probably needs this too).

License badge isn't quite correct, since placeholder on crates.io is purely MIT licensed, if marker-crate-reservations can be dual-licensed, like all other repos, and updated on crates.io, that would be great!

Context:

• rust-lang/rust@2a8807e
• Remove appendix from LICENSE-APACHE serde-rs/serde#2355
• Remove appendix from Apache license rust-lang/rust#67734
• sync license files with rustc repo rust-lang/miri#1846

@xFrednet I don't think there's much to review here, just requires an action from you to update the placeholder crate, I'm going to mark this as blocked for now, feel free to do that whenever you want

[xFrednet]

Hope my comments are not too nit picky 😅 We should also check that the licenses are correct in the Cargo.toml files for crates.io

The placeholder crates can remain, as they are right now. Old versions can't be removed/modified anyways. The new licenses will be updated on crates.io when we push the version from this repo. Thank you for pointing it out though :)

The badge takes licensing information from crates.io, not the github repo, that's why the crates need to be updated

Looks like we have another reason to look forward to that day. ^^ IDK if I can reach the goal of completing the AST representation by March, but I want to be optimistic.

We'll wait on the merge until the first version has been published, to ensure that the license shield is correct. If you want, you can also remove that line and r=me. Then we can add it back with the first version :)

Thanks!

I don't like merging this with a wrong badge, I think what I can do is hardcode the badge for now, and make it link to the crates later. Or we can just leave this as blocked until the license has been updated, as it's not really urgent and shouldn't conflict with anything

[xFrednet]

I'm fine with either option. Even if there will be conflicts, they should be simple to resolve. I'll add this to the milestone, to merge is shortly before releasing the crates :)

[Niki4tap]

Sure, I'm fine with leaving this blocked then

[xFrednet]

Thank you for this PR! I'm currently updating the license information of the crates and README.md files as part of #151. I'm closing this PR in favor of that issue.

Thank you, for the work you did, I highly appreciate it!
