Incorrect SpEL example in reference documentation [SPR-16111]

[spring-projects-issues]

Sviatoslav Hryb opened SPR-16111 and commented

Spring Framework Reference Core Technologies https://docs.spring.io/spring/docs/current/spring-framework-reference/pdf/core.pdf contains incorrect code fragment in section 4.5.6. Methods.
The incorrect code fragment is: ```
// string literal, evaluates to "bc"
String c = parser.parseExpression("'abc'.substring(2, 3)").getValue(String.class);

Because string literal, evaluates to "c" but not to "bc"

Good catch, I've fixed this towards substring(1, 3).

FWIW, this is not a 'critical' framework bug. We consider such documentation glitches as minor tasks only.
