Fix broken links and setup errors in time series tutorials

[Valyrian-Code]

Fixes 5 issues across two time series tutorials:

time_series_management_and_visualization.qmd

• L270: t.register linked to grass83 manual (301 redirect) → updated to grass-stable
• L297: g.gui.tplot linked to grass83 manual (301 redirect) → updated to grass-stable
• L427: t.rast.univar linked to t.vect.univar.html (wrong tool) → fixed to t.rast.univar.html

time_series_aggregations.qmd

• L48: undefined variable grassbin in hidden setup cell → replaced with string "grass" (consistent with all other tutorials in the series)
• L55: wrong project path eu_laea/italy_LST_daily → corrected to italy_eu_laea/italy_LST_daily

The aggregations bugs are in a #| echo: false cell — invisible in the rendered tutorial but break execution in the downloaded Jupyter notebook.
