[MC-279153] Some strings that mention the base values of attributes are missing articles

The Bug:

Some strings that mention the base values of attributes are missing articles.

For a bit of context, there are three articles within the English language. These are "a", "an", and "the". Articles are used before nouns. Considering that articles are present throughout many other strings within the game, this introduces an inconsistency.

Affected Strings:

Before reading the table, please note the following:

Words colored in GREEN are correct.
Words colored in RED are incorrect.

Translation Key	Current String	Expected String	String URL on Crowdin
commands.attribute.base_value.get.success	Base value of attribute %s for entity %s is %s	The base value of attribute %s for entity %s is %s	https://crowdin.com/editor/minecraft/10038/enus-engb?view=comfortable#5340974
commands.attribute.base_value.set.success	Base value for attribute %s for entity %s set to %s	The base value for attribute %s for entity %s set to %s	https://crowdin.com/editor/minecraft/10038/enus-engb?view=comfortable#5340976
commands.attribute.base_value.reset.success	Base value for attribute %s for entity %s reset to default %s	The base value for attribute %s for entity %s reset to default %s	https://crowdin.com/editor/minecraft/10038/enus-engb?view=comfortable#5382614

Steps to Reproduce:

```
/tellraw @s {"translate":"XYZ"}
