presignUrl with write permissions and BYO credentials fail on PUT Blob

[moritzraho]

Expected Behaviour

write permissions should allow to send a PUT request to the presignURL even with BYO credentials

Actual Behaviour

This is failing for BYO credentials:

• const files = await Files.init({ azure: {mycreds} })
• const url = await files.generatePresignURL('hello.txt', { expiryInSeconds: 500, permissions: 'w' })
• await fetch(url, { method: 'PUT', body: 'hello23' }) => returns 400 missing header (seems that it wants the Authorization header)

same works fine with TVM credentials
