Import attributes support

[lucsky]

Hello, does Rollup support TC39 import attributes (https://github.com/tc39/proposal-import-attributes) which was also recently added to Typescript 5.3 ? The documentation only seems to mention the old deprecated syntax (which uses the assert keyword).

The syntax is supported, but it is currently rendered as "assert" in the output as the "with" syntax is not widely supported: https://rollupjs.org/repl/?version=4.9.0&shareable=JTdCJTIyZXhhbXBsZSUyMiUzQW51bGwlMkMlMjJtb2R1bGVzJTIyJTNBJTVCJTdCJTIyY29kZSUyMiUzQSUyMmltcG9ydCUyMGZvbyUyMGZyb20lMjAnZXh0ZXJuYWwnJTIwd2l0aCUyMCU3QnR5cGUlM0ElMjAnanNvbiclN0QlM0IlMjIlMkMlMjJpc0VudHJ5JTIyJTNBdHJ1ZSUyQyUyMm5hbWUlMjIlM0ElMjJtYWluLmpzJTIyJTdEJTVEJTJDJTIyb3B0aW9ucyUyMiUzQSU3QiUyMm91dHB1dCUyMiUzQSU3QiUyMmZvcm1hdCUyMiUzQSUyMmVzJTIyJTdEJTJDJTIydHJlZXNoYWtlJTIyJTNBdHJ1ZSU3RCU3RA==
