docs: make the documentation for --etag-save match the program behaviour When using curl with the option `--etag-save` I expected it to save the ETag without its surrounding quotes, as stated by the documentation in the repository and by the generated man pages. My first endeavour was to fix the program, but while investigating the history of the relevant parts, I discovered that curl once saved the ETag without the quotes. This was undone by Daniel Stenberg in commit `98c94596f5928840177b6bd3c7b0f0dd03a431af`, therefore I decided that in this case the documentation should be adjusted to match the behaviour of curl. The changed save behaviour also made parts of the `--etag-compare` documentation wrong or superfluous, so I adjusted those accordingly. Closes #7429

This option makes a conditional HTTP request for the specific ETag read
from the given file by sending a custom If-None-Match header using the
stored ETag.

For correct results, make sure that the specified file contains only a
single line with the desired ETag. An empty file is parsed as an empty
ETag.
