Backport #39782 by @basavaraj-sm05
The RubyGems compact index (the shared `/versions` file and per-package
`info/<name>` files) is line-based.
https://github.com/go-gitea/gitea/pull/38061 rejected line breaks in the
gem name, but the platform, dependency names and version requirements
from the gemspec still accepted them, letting an uploader forge index
lines for bundler clients.
The parser now rejects a line break in any of those fields. The Marshal
based endpoints are length prefixed and unaffected.

The registry writes the stored gem name straight into its line-based
compact index, both the shared `/versions` listing (one `GEMNAME
versions md5` line per gem) and the per-package `info/{name}` file. The
parser only rejected an empty name or one containing a slash, so a
`.gem` whose gemspec `name` carries a newline was accepted and persisted
as the package name, letting an authenticated uploader forge extra lines
in the shared index and so spoof additional gem names, versions and
checksums to clients. The name is now checked against the upstream
RubyGems name pattern in the parser, which is the layer that already
validates the version.
