Fixed #33253 -- Reverted "Fixed #32319 -- Added ES module support to ManifestStaticFilesStorage."

This reverts commit 91e21836f667c784a8a63ab1f18d81f553e679cb.

`export` and `import` directives have several syntax variants and not
all of them were properly covered.

Thanks Hervé Le Roy for the report.
