Mihai Parparita 63ad49890f cmd/tsconnect: pre-compress main.wasm when building the NPM package
This way we can do that once (out of band, in the GitHub action),
instead of increasing the time of each deploy that uses the package.

.wasm is removed from the list of automatically pre-compressed
extensions, an OSS bump and small change on the corp side is needed to
make use of this change.
