### Does this PR introduce _any_ user-facing change?
Yes. E.g., before this change, we may have an error
```
scala> spark.sql("SET non-existent-key")
org.apache.spark.sql.catalyst.parser.ParseException:
Expected format is 'SET', 'SET key', or 'SET key=value'. If you want to
include special characters in key, or include semicolon in value, please use
quotes, e.g., SET `ke y`=`v;alue`. (line 1, pos 0)
== SQL ==
SET non-existent-key
^^^
```
After this change, the error message becomes
```
org.apache.spark.sql.catalyst.parser.ParseException:
Expected format is 'SET', 'SET key', or 'SET key=value'. If you want to
include special characters in key, or include semicolon in value, please use
quotes, e.g., SET `key`=`v;alue`. (line 1, pos 0)
```
### How was this patch tested?
No tests needed, as the change is straightforward and simply to text
formatting.
