Caption misused as name

[paulremo]

Throughout the book, captions are reused as names of elements. This complicates the readability of the sources and causes warnings when compiling the LaTeX document (#38).

Instead of:

(meca_table4_5)=
```{list-table} Possible interactions between different mechanical failure mechanisms
:class: interactive-table
:name: Possible interactions between different mechanical failure mechanisms

* - some content

the following should be written:

:class: interactive-table
:name: meca_table4_5

* - some content

This was fixed as part of #52.
