Replace new "fixed %s bugs" string with a pre-existing one

[SergeyBiryukov]

[45359] introduced a new string on the About page:

_n(
	'<strong>Version %1$s</strong> fixed %2$s bug.',
	'<strong>Version %1$s</strong> fixed %2$s bugs.'
	...
);

It should be replaced with a pre-existing string​:

_n(
	'<strong>Version %1$s</strong> addressed %2$s bug.',
	'<strong>Version %1$s</strong> addressed %2$s bugs.'
	...
);

@SergeyBiryukov and @desrosj i can't found [45359] changeset in ​WordPress GIT repo and SVN but those changes are shown in Beta Testing WordPress plugin with Point release nightlies option.

When we got those changes in GIT or in SVN?

[mukesh27]

Got it from 5.2-branch in GIT. attached patch for changes.

[mukesh27]

Patch.

[desrosj]

There's going to be a 5.2.1. RC2 because of #47323. Let's just fix this before release.

[desrosj]

@mukesh27 [45359] was not committed to trunk, only the ​5.2 branch.

47312.diff​ looks good. Tagging for a second review.

[desrosj]

The number of bugs will also need to be updated to 33 to reflect #47304 being included.

[SergeyBiryukov]

Replying to desrosj:

The number of bugs will also need to be updated to 33 to reflect #47304 being included.

With both #47304 and #47323, wouldn't it be 34?

[desrosj]

I did not count it because it was a bug introduced during the 5.2.1 cycle and was not something that made it into the wild. I don't feel strongly about not including it, though.

[SergeyBiryukov]

Ah, makes sense :) 47312.2.diff​ updates the count.

[desrosj]

In 45364:

Help/About: Replace minor release strings with pre-existing ones.

Also, update the number of bugs fixed in 5.2.1 to include those being fixed after RC1.
