az storage azcopy blob changes underscores to dashes.

[rafaelrruiz]

Describe the bug

az storage azcopy blob seems to be changing underscores in our destination name to dashes. This causes issues for some files that must adhere to certain naming schemes (such as CLI extensions).

Related command

We were using this: az storage azcopy blob upload --account-name $DESTINATION_STORAGE_ACCOUNT_NAME -c "cli-extension" -s "./$DESTINATION_FILE_NAME" -d "$DESTINATION_FILE_NAME" --output table --debug

But had to switch to this because the underscores in DESTINATION_FILE_NAME were being changed: az storage blob upload --account-name $DESTINATION_STORAGE_ACCOUNT_NAME -c "cli-extension" --output table --name "$DESTINATION_FILE_NAME" --file "./$DESTINATION_FILE_NAME" --debug

Errors

No error, file name is changed.
