[TF2] fix: wrong concatenated item event name due to missing comma

[CosminPerRam]

Description

Fixes an item event name being wrongfully concatenated due to missing comma in the const char list.

Before:

        "item_removed_attrib",
	"item_changed_style"

	// NEW STORE EVENTS
	"store2_entered",

Resulting in "item_changed_stylestore2_entered" being an entry.

This has a compilation error when compiling

error C2338: static_assert failed: 'Compile time assert constraint is not true: ARRAYSIZE( g_ItemEventNames ) == IE_COUNT'

The last line should be removed or commented

"" // IE_COUNT

Ooops, somehow missed that, I think it failed to build and I ran the last successful build, will fix soon.

Fixed, thanks @Bitl

This will fix ItemEventID in the OGS DB in the following cases:

Event	Old	New
IE_ITEM_CHANGED_STYLE	item_changed_stylestore2_entered	item_changed_style
IE_STORE2_ENTERED	item_reset_counters	store2_entered
IE_ITEM_RESET_STRANGE_COUNTERS	item_put_into_collection	item_reset_counters
IE_ITEM_PUT_INTO_COLLECTION	""	item_put_into_collection

IE_ITEM_PUT_INTO_COLLECTION is not used in TF2, but this change could affect some other usage if applicable.
