This is a regression accidently introduced in #9957.
A delete call had been used on the Template key of vals. This caused
a condition where Template was not available when rendering via tpl.
The delete happened after ExecuteTemplate so the issue is surpsising.
It may possibly be a race condition. Existing tests did not catch it.
I tried to create a test that directly tested the issue and was
unable to replicate the error seen with real charts. This leads me
to believe it is a race condition in the underlying Go template
package.
The delete call was not there before #9957. It should be safe to
remove and keep that information.
Closes#10082

The templating engine handles errors originating from the `required` and
`fail` template functions specially, cleaning up the error messages to
be more presentable to users. Go's text/template package unfortunately
does not make this straightforward to implement. Despite
template.ExecError implementing Unwrap, the error value returned from
the template function cannot be retrieved using errors.As. The wrapped
error in ExecError is a pre-formatted error string with the template
function's error string interpolated in with the original error value
erased. Helm works around this limitation by delimiting the
template-supplied message and extracting the message out of the
ExecError string with a regex.
Fix the parsing of `required` and `fail` error messages containing
newlines by setting the regex flag to make `.` match newline characters.

This fixes#6044, in which error parsing is greedily eating too many
colons, preventing users from using colons in their warning messages to
the `required` function

Have updated the required filter so that it doesn't break when linting a
chart. This work is based off #4221 and #4748 which didn't make it into
the v3 branch.

Make template specific functions private to ensure they not misused and
make unit tests simpler. We may export the template helpers later if
needed.
This lays the foundation for the new chart pipeline.

This sorts templates by depth before sending them to the template
parser. Deepest templates are parsed first, with umbrella templates
parsed last. Since template definition names are LIFO, that means that
the highest level templates will claim the namespace.
Or, to put it simply, you can predictably override a child's defined
template by re-defining it in a parent chart.
