fix: replace LICENSE files with exact official Apache 2.0 text (#356)

pkg.go.dev license detection requires an exact match against the
official Apache 2.0 template. The previous LICENSE files had minor
textual deviations (e.g. 'the Licensor' vs 'Licensor', modified
appendix section) that prevented detection.

Both root LICENSE and vscode-extension/LICENSE now use the verbatim
text from https://www.apache.org/licenses/LICENSE-2.0.txt
