Unconditional access to global __VUE_PROD_DEVTOOLS__ breaks SSR

[s-ol]

Reporting a bug?

vue-i18n attempts to read a global __VUE_PROD_DEVTOOLS__ variable. This causes a ReferenceError in some engines, especially in an SSR context with recent node versions:

ReferenceError: __VUE_PROD_DEVTOOLS__ is not defined
    at Object.install (file:///home/s-ol/dot/vike-repro/node_modules/vue-i18n/dist/vue-i18n.mjs:2284:65)

See also vikejs/vike#1778 (reply in thread).

Expected behavior

globalThis shoud be checked using '__VUE_PROD_DEVTOOLS__' in globalThis before attempting to read the variable.

Reproduction

The i18n branch in this repository illustrates the issue using vike-vue: https://github.com/s-ol/_vike-vue-i18n-repro/tree/i18n
