lib: fix typos in esm loader comments

[RonGamzu]

Fixes three typos in comments in the importSyncForRequire path of
lib/internal/modules/esm/loader.js:

• "check the whether" → "check whether"
• "kEvaluaing" → "kEvaluating" (matches the symbol used elsewhere in
  the file, e.g. the import on line 53 and the comparisons on lines
  340 and 382)
• "the the problematic" → "the problematic"

Comment-only change; no functional impact.
