chore: Align and update MIT license dates

[AbhiPrasad]

In getsentry/sentry-python#3029 it was raised that we need to make sure the SDK MIT License has an up-to-date year. We also need to make it a range.

In this PR I went ahead and updated the dates accordingly, changed the license to directly reference Functional Software, Inc. dba Sentry, and re-aligned all the Licenses of individual packages to have the same format and structure.
