(#525) Bump version to 2.7.0

[st3phhays]

Description Of Changes

This bumps the version of all packages to their latest minor or patch versions. In addition, this upgrades Astro to version 6.x, which then resolves it's dependencies to the needed versions.

Astro now requires Node.js: >= 22.12.0.

Motivation and Context

It is best to stay up to date with dependencies' new versions to bring in new features, fixes, and security updates.

Testing

1. Ensure that you are on Node >= 22.12.0 by running node -v. If you are not, Run nvm install latest and then nvm use latest.
2. Pull down this PR.
3. Run yarn and yarn audit and ensure it passes with "No Audit Suggestions".
4. Run the website and ensure all is good. If the website has automated tests, ensure they all pass.
