feat: add default lang and global scope plugin options for SFC i18n custom block

[userquin]

closes #108

Also added .idea/ directory to be excluded on .gitignore (intellj/webstorm stuff).

[userquin]

Maybe options names can be others...

Thank you for your PR!

Sorry, currently, I'm a little busy with my day job. 🙇
I'll try to check your PR later. 😉

I need to add docs for these 2 new options (but first I'll wait for your feedback, once ok I can add docs) and also on the site (at least here: https://vue-i18n.intlify.dev/guide/advanced/sfc.html#bundling-with-vite, and here https://vue-i18n.intlify.dev/guide/advanced/sfc.html#bundling-with-rollup (for webpack I need to review options), but it is is another repo).

I've just checked your PR!

Could you add these options docs to README please?

give me a few minutes

I only add it on options section (with an example), do you want I add something on i18n custom block section?

[userquin]

Don't merge yet.

I'll add a warning, since globalSFCScope cannot be disable once configured (global attribute has no values).

For defaultSFCLang I need to add a hint: it can be overriden using i18n lang custom block attribute.

[userquin]

Done
