fix: generate d.mts for .mjs files

[JLHwung]

In abf6544 we shipped a breaking change that renames *.js to *.mjs, which leads to the following tsc error:

TS2307: Cannot find module '@unicode/unicode-16.0.0/Binary_Property/ID_Start/ranges.mjs' or its corresponding type declarations.

as tsc expects d.mts files for .mjs inputs.

Thanks!

@mathiasbynens Could you tag a 2.0.6 release? Babel depends on this change.

@JLHwung On it!

[JLHwung]

Thank you. The published package now contains both .d.ts and .d.mts: https://github.com/node-unicode/unicode-18.0.0/tree/v2.0.6/Bidi_Class/Arabic_Letter

I will check if tsc is happy with that.

I guess we should uncomment this line the next time we publish:

node-unicode-data/bootstrap.sh
