fix: use windows-compatible filename (#1070)

Cloning the JSR repository may yield errors on Windows, which seems to
stem from the `cloudtrace:v2.ts` file. This is because [semicolon may
not be a valid character in file
names](https://stackoverflow.com/a/31976060).

To make it easier for Window's users to contribute without errors, I
suggest renaming `cloudtrace:v2.ts` to `cloudtrace.v2.ts`.
