fix(compiler): small improvement to error message handling

[Vikash9546]

What problem exists

A small typo/grammar issue in parseErrorForMissingSemicolonAfter's documentation can be a minor distraction when working on parser diagnostics.

Why this change is useful

This PR corrects wording in two nearby comments in src/compiler/parser.ts, making the intent clearer without changing any compiler behavior.

Files modified

• src/compiler/parser.ts

Tests

• Not added (comment-only change).
• Local verification: npm run build.
• Note: npm test fails locally with EMFILE: too many open files, watch in unittests:: sys:: symlinkWatching:: (environment/FS watcher limit); the change does not affect runtime or test logic.
