Description

I think this fix is not the ideal way but at least it works.

The reason why #8498 (comment) was happening is:

1. Vite decodes URL (%252ffoo.txt => %2ffoo.txt)
2. Vite filters URL (%2ffoo.txt)
3. sirv decodes URL (%2ffoo.txt => /foo.txt)
4. sirv reponses (/foo.txt)

The file path mapped from URL is different between 2 and 4.

This PR adds encode after 2. (%2ffoo.txt => %252ffoo.txt)

fixes #8498
refs #8804
refs lukeed/sirv#139
