Fix references and redundant text in Psychological Safety guide

[Copilot]

Four reference and text issues in the Psychological Safety guide caused citation mismatches and reader confusion.

Changes

• Removed redundant text: Eliminated duplicate "(mutual support)" from Mutual Support behavioral pattern description
• Added missing Lencioni reference ¹: Restored citation for "The five dysfunctions of a team" referenced in constructive conflict discussion
• Corrected Edmondson citation ²: Fixed "3 types of failures" to reference "Right kind of wrong" (2023) instead of Kerth
• Added Kerth reference ³: Restored correct citation for retrospective prime directive quote

Reference Corrections

Before:

• ² pointed to Kerth for both Amy Edmondson's failure types AND the retrospective quote
• ¹ was missing despite being referenced for Lencioni's model

After:

All citations now follow the established academic format.

<issue_title>[Psychological Safety in Scrum Teams] The text correction is need and fix for references</issue_title>
<issue_description>### Type of Change

Content correction/fix

Section/Area Affected

The expansion "Psychological Safety in Scrum Teams"

Current Content

MISTAKE 1:
Mutual Support: When supporting a teammate under pressure means sharing responsibility for outcomes rather than protecting individual credibility (mutual support).
--> "(mutual support)" should be removed

MISTAKE 2:
see also Lencioni’s model in ¹
--> reference to the book is broken and it's not visible on the list of the references, here is the reference: Lencioni, P.M. (2012) The five dysfunctions of a team: Team assessment. Hoboken, NJ: John Wiley & Sons.

MISTAKE 3:
There is an incorrect reference here:
Amy Edmondson defines 3 types of failures [reference] --> currently it links to Kerth, N.L. (2013) Project retrospectives: A handbook for team reviews. Boston, MA: Addison-Wesley.; while it should be: Edmondson, A.C. (2023) Right kind of wrong: The science of failing well. New York: Simon & Schuster.

MISTAKE 4:
"“Regardless of what we discover, we understand and truly believe that everyone did the best job they could, given what they knew at the time, their skills and abilities, the resources available, and the situation at hand”³." --> reference is broken, it should be: Kerth, N.L. (2013) Project retrospectives: A handbook for team reviews. Boston, MA: Addison-Wesley.

Proposed Change

Remove "(mutual support)". Fix missing references and update references so that they are correct.

Rationale

Currently the reader might be confused.
