Doc: Replace all relative links like `../reference/sage/graphs/graph_generators.html` by `:ref:`, `:mod:`, `:class:` etc.

[mkoeppe]

All of these should be replaced by proper references using the :ref: Sphinx role, or, for most links to the reference manual, using :mod:, :func:, :class:` etc.

When there is no label that can be linked to, create one.

[Nidhi-Sharma9419]

Can I work on this issue?

[Nidhi-Sharma9419]

Command sage --docbuild is not working on my pc. Is there any other I can check my changes?

[mkoeppe]

Create a PR with your changes, then the docbuild will be run there

[Nidhi-Sharma9419]

There are some links which don't work or those files don't exist , for e.g. src/doc/en/thematic_tutorials/sandpile.rst: <../reference/sage/graphs/graphgenerators.html>`

Should I leave them as it is without doing any changes?

[mkoeppe]

This links to the automatically generated documentation for the module sage.graphs.graph_generators. This should be replaced by use of the appropriate Sphinx role:

:mod:`sage.graphs.graph_generators`
