Remove some strengthened comments

[pjessesco]

Fixes #2403

[fsb4000]

Note: constexpr default_sentinel_t end() const noexcept doesn't have strengthened comment, so we don't remove the comment here.

STL/stl/inc/ranges

Lines 3513 to 3515 in 303df3d

	_NODISCARD constexpr default_sentinel_t end() const noexcept {
	return default_sentinel;
	}

Thanks for your contribution! Many of the maintainers are currently "out of the (virtual) office" due to the end-of-the-year US holidays, so it may take us a little longer to review your changes due to reduced bandwidth. Thanks for your patience, we'll take a look as soon as we can! 😄
