scala-cli setup-ide generates files in latin-1 instead of utf-8

Describe the bug

scala-cli setup-ide generates .bsp/scala-cli.json in latin-1, while it should be encoded in UTF-8 (I was unable to check the other files).
This breaks the integration with metals for users with a home on a non-ASCII path.

To Reproduce

• Set your scala-cli instalation directory to somewhere with a non-ASCII character (in my case: C:\Users\João\AppData\Local\Coursier\data\bin\.scala-cli.aux.exe)
• Run scala-cli setup-ide
• Check the .bsp/scala-cli.json file (in my case, the ã was encoded as 0xe3)

Expected behaviour

I would expect the file to be encoded in UTF-8.

In my case, I would expect the ã to be encoded as either 0xc3 0xa3 (LATIN SMALL LETTER A WITH TILDE) or 0x61 0xcc 0x83 (LATIN SMALL LETTER A with COMBINING TILDE).

scala-cli setup-ide . --charset utf-8 seems to do the trick. I would expect this to be the default, as metals won't work otherwise.

I imagine the answer to https://github.com/VirtusLab/scala-cli/blob/9385014b9a0207f3234cd1d4cf378aba5f46555e/modules/cli/src/main/scala/scala/cli/commands/setupide/SetupIde.scala#L167C1-L167C66 is "yes"
